Let's say, ALL heroes vs Illidan will wait for evasion to expire while kiting, then start dealing max dmg while retreating, if not better surviveability guide.
Against Jaina, you can make her use lance by coming super close, wave with Windfury, escaping Blizz and she Cones you in the face, maybe even landing ring or elem. Them, depending on a situation, if enemy team chases you/she has +25% dmg debuff or freeze talent on her cone, you super surely turn back... If don't have a healer in a proper position to heal you safely.
In 1x1, you can rape her in the pose you want mostly, even if you dodged only 1/2 Blizzard and ate lance before.
ALso, it's not a sin to make 3-4 charges of FwR, to heal right after her skill and maybe one more time. Her elemental can give a couple of stacks if close enough to Chain and ultimate, ofc, the problem is he can damage from quite good distance.
Also, good to know that ring works only at the ONE MOMENT, and only at it's perimeter, not center. Wait for it... Wait for it... Boom! GO!
Just wanted to say it's not so bad to face Illidan or Jaina 1x1.
If picked Rabbit Wolves *,.,* in Tier 1, it's even better. wait for his roll over + flight in front and land wolf to heal. Ofc, this part is kinda risky still. Illidan cooldown reducing powa is mad.

Why is giant killer not a option for thrall?
With wind fury giving you twice as many attack speed and Tempest Fury giving your last wind fury hit 3 basic attacks for 75% damage isn't giant killer really good on thrall?
with giant killer hitting 1,5% hp of your opponent your last wind fury hit will hit 4.5% of your opponent hp instant and during wind fury total 7,5%.
Instead you get extra stacks of Frostwolf Resilience which is good for sustain but is it always better?

Also seasons marksman is a no go, but landing your Feral Spirit will only give you +2 stacks which is good if you land it but if you don't you just lost 2 extra stacks. Mostly when you go in with thrall you feral spirit someone, and when you go in you are already on full hp or near full hp. Season marksman can grand you your extra damage to burst someone down. Because your engage time with thrall is mostly on the short side since people won't go a 1 vs 1 on melee range with thrall isn't season marksman a good option?
If you got a comp with 2 healers you don't really need the sustain of your Frostwolf Resilience, I would go for the most burst damage I could get and take season marksman and giant killer.
I know the sustain build with thrall is mostly better in the meta of one healer but saying it is not done to take giant killer and season marksman is a bit off, if you ask me.

I agree about everything in this build, except the first talent. Rabid Wolves allows you to heal more, yes, but not when you need it.
I play Thrall a lot, I always heal myself between fights, either on enemy walls, minions, or even merc, and I never engage with less than 2 stacks of Frostwolf, so I think block help engaging but mostly escaping, after they dropped all they had and nearly kill you, Rab wolves heals more sure, but you usually engage with it, so it heals you for nothing, and then you get bursted down, when block can( not will) keep you alive. It becomes more useless over time, when you can pratically heal all your hp with windfury + chain lightning.
I also pick rolling thunder when the enemy team as a long range and I need to poke a lot, as well as heal les but more often

Very good guide, however there are some utility/synergies that could be worth mentioning in the skills section and the Talent section. Also, I am not saying your Talent choices are inferior, just that people should know what they are giving up for making the talent choice. (Sorry for the long list)

Feral Spirit-can be used as an AoE on a minion wave which is very useful for getting Frostwolf Resilience stacks for sustain when pushing a lane.

Sundering-Similar to above, has an AoE skill shot that can rack up Frostwolf Resilience stacks. An occasional downside to this skill is the displacement could hit enemies out of a friendly AoE/skill shots such as Blizzard or Mosh Pit. Also great for interrupting channeled abilities like Triple Tap.

Ride The Lightning-is actually very comparable to Rabid Wolves as it gives Chain Lightning an extra chance for two extra stacks of Frostwolf Resilience and the small damage increase is really just a cherry on top. The downside is that these two stacks are not guaranteed in team fights if they aren't close enough together.

Spirit Journey-additional range on the root is fairly useful for chasing an enemy, but this talent really just works with Stone Wolves for this purpose.

Follow Through-when using this talent as the potential to add in an additional 120% of an auto attack when Thrall uses Windfury to reach the target, Auto, Feral Spirit, Auto, Chain Lightning, Auto. This means relying on only Windfury to engage while Feral Spirits roots the target in place for the last two hits.

Giant Killer- synergy with Tempest Fury as Windfury would also take 7.5% max health. Works well with either Wind Shear or Follow Through at level 7.

Great guide! Excellent detail and insight into the hero :)

Thumbs up here, starting to really love playing Thrall!

I've tried your build out a lot and i truly recommenced it, ive come out top hero damage almost every time. GG

I've tried both and I can say that I haven't seen a huge difference in the midgame after taking either Follow Through or Wind Shear. It's definitely better getting the lower CD in the early game, because you can run away more times, but Follow Through also serves its purpose likewise, due to the fact that you can generate tons of damage if you train on how to use it, meaning that you won't have to run away as much :)

@HidaHayabusa Follow Through is not that bad of a choice in general, but Wind Shear offers so much utility, because Windfury is not only your biggest damage ability, but also your only escape until level 20. This is how I see it: If you can use Windfury twice in a teamfight due to that cooldown reduction, Wind Shear is better than Follow Through. About the 100-0 part, this is why I pick Tempest Fury at level 16. Lastly, I almost always use Feral Spirit and immediately after Windfury, which makes me lose that one auto-attack. In general, I don't like the mechanic of using my spells between the auto-attacks of Windfury, but if you feel like you can pull it off, then definitely go for it.

You seem to rate Follow Through as being a bad choice on its tier, by saying that it depends on landing auto attacks in between spells. Isn't this what Trhall is all about? I understand that Windfury is the bread and butter of the DPS output, but really Follow-Through synergises so well with it that it's almost helping to 100-0 anything in a full Windfury duration, especially if you manage to land a Chain Lightning/Wolf in between.

@izzack Concerning the mana problems, I usually prefer Mana Tide on level 4 instead of Rolling Thunder on level 1, but that's just personal preference I guess. About the Illidan, it's true that after level 16 you can pretty much burst him down, if you time your Windfury right. However, in the early game I usually struggle against Illidan in lane, due to the constant harass and the wave clear after level 4. To be honest, my comment about the 1v1 against Illidan wasn't clear enough, so I just removed it.

Great guide, pretty much the only playable build on Thrall which is a bit shame. Basically only matter of discussion is first tier of talents. Personally prefer Rolling Thunder to Rabid Wolves as I tend to have mana problems a bit early on, and it helps to clear minion waves a bit faster when you can spam your Q. But from my own experience I disagree with Illidan comment. I have always beaten up Illidan in 1v1, as long as you are at least lvl 16, so you have lower CD, higher sustain and dmg on E. And obviously, bread and butter against Illidan, use E after his evasion fades.
