The sentry heroic needs a rework. It seems just much weaker than time warp, considering that time warp is a global earthquake. Maybe the heroic could be replaced with warp in, which warps in a large number of units and lets you control them, even without the micro talent.

I have to disagree with the choice of Energy Roil at level 1. I decided to test out Fel Infusion once, and I consistently had no mana to do much of anything. Kael'thas is very strong when you can throw spells around and absolutely blow up your opponents, but you need mana for that. Also, collecting regen globes becomes pretty natural after a few games with the talent. Great guide though.

Agh, the removal of Ignite hurts, and Fury of the Sunwell isn't exactly placating me, since you seldom land both hits. I do enjoy being able to slow the whole enemy team, but I miss the damage and poke that came from flamethrower ignite.

Having played Warcraft III, this concept is very close to my heart. I feel like I would enjoy playing this hero immensely. Also, I think that vengeance should function more like it does in Warcraft. For every some amount of damage dealt to ANY TARGET, it would summon shadow spirit. It would also have substantial health, so it would be a threat that would take some effort to focus. That's my idea, anyway. I like this concept in general though.

I absolutely love this concept. Before HotS came out, I spent a lot of time playing a MOBA like game in the Starcraft arcade - Hero Attack. In that game, Reaper was my favorite character, and I feel that you've represented him very well here. While it may need some balancing, I think his extreme mobility is a core part of the reaper, and I really like how you've done it here. I feel as if his ults could use some changing (maybe have one that increases mobility further or something?), but all...

I completely love this build, except I use stoneskin whenever I pick metamorphosis. Even with the heal buff, I feel that picking talents that benefit off of YOUR max health has better synergy with metamorphosis. It's like picking first aid - more health gives you more survivability. Also, what Illidan needs for his lifesteal on his passive to keep him alive is damage mitigation, which is why I like stoneskin. BFB is still pretty fun, but I only pick it when I go yolo hunt because the increase...

I feel like the change to double bombs kind of forces you to get closer to your opponents. Previously, you use to be able to use 2 spikes and just burst someone down, but now, you need to use your cleave to do the damage you need. Unless you catch someone really low on HP, 1.5 Singularity Spikes won't be enough. Now, I feel like the real benefit of the second bomb is the slow, since it allows you to get that cleave damage in there. I'm finding that the combo I have to use now to deal enough...
