Introduction:
This guide is designed for newer players, or more experienced players looking for a capable but resilient hero. I have also crafted a guide that focuses more on damage-dealing (especially in the late game) if that better suits your needs.

A note for those new to Heroes of the Storm:
As with all guides, this is just a recommendation. I myself will deviate from my own guides depending on the situation in-game sometimes. If you find any hero to your liking, you should experiment with their talents. You may find a combo you like that isn't in a current build, and that's great! That being said, guides are great for just starting out with a hero. If this one proves useful to you, I am glad. Enjoy your time in HotS!

Talent Choice Explanations:
Below I explain not what each talent does (you can find that out easily), but why I choose each talent.
Level 1: Give me More!
Gives you more. Adrenaline Rush is Raynor's greatest strength, allowing both new and seasoned players an extra level of forgiveness for overstaying their welcome in lanes or fights. It also comes in handy in the late game, allowing you to stick around for that final push (even though Raynor's Raiders, which we'll get to later, can cover for you while you back off to keep alive). Beefing it up is almost never a bad idea.

Level 3: Vigorous Assault
I think these got redesigned recently. Or maybe the icons just changed. I don't know. We once again buff healing here, this time by life stealing with our basic attack. Since Raynor really only has one attacking ability (besides his heroic, which has a long cooldown), you will find yourself doing A LOT of basic attacking. Why not get yet more health for doing so?

Level 7: Revolution Overdrive
Now I know I said earlier that beefing up Adrenaline Rush (your healing ability) is ALMOST never a bad idea. This is one of the few times where that almost comes into play. Heroes in Heroes of the Storm are SLOW (with a few exceptions like Lunara). Having the 10% speed boost granted by this ability (or more if you cast it when allies were around) really does make a difference when chasing down an enemy or running away.

Level 10: Raynor's Raiders
All right, so you heal a lot and can move a bit faster than most. But you're a bit lacking on the damage-doing side. That is about to change. Think of Raynor's Raiders as a secondary hero that you can get to do your dirty work for you. Use it to chase down heroes making a hasty getaway after a teamfight. Or target the enemy's keep or core to do your fair share of damage while keeping enemy heroes at bay (by killing them).
A tirade about Hyperion and why you shouldn't choose it:
It seems like everyone, especially newer players, builds Hyperion. The Bots build Hyperion. I too was guilty of this when just starting out. But I tried Raiders instead one game and got hooked. The problem with Hyperion is it is too unfocused. While launching it in a teamfight can scatter and perhaps do damage to enemies, it is relatively easy to dodge if you aren't right in the middle. In fact, the biggest chance of killing an enemy at even half health with Hyperion is If they run into hostile towers while avoiding it. Compare that to Raiders, where you select a target, whether it be a structure or enemy hero (Hyperion is also awful at taking structures (because AoE)). This allows you a much greater level of control over what is getting hit, and does far more damage to that object. It also isn't easy to evade, meaning heroes like Valla or Lunara can't just jump out of the line of fire. This is just my opinion obviously, and if you have found Hyperion to work for you that's great. Just give Raiders a try, please.

Level 13: Double Barreled
Shoot twice as many things for the rest of the game. Some choose Giant Killer here, and that's fine if you're leveraging basic attacks, but I find giving Q some extra attention instead goes a long way and will come in great handy when you need to land the killing blow.

Level 16: Bullseye
All talents in HotS are situational. If you find your aiming is on point and you are hitting targets consistently, Bullseye is the way to go. However, if you aren't quite as consistent this game or your enemies are fidgety, Cluster Round can be quite nice in massive, clumpy teamfights.

Level 20: Ehh
I admit, this is a gray area for me. The level 20 talents just aren't that spectacular. I would say your best bet is Nexus Frenzy. Its a nice boost overall. Alternatively, Dusk Wings may come in handy, especially if you're in the lead and pushing. A Card to Play may be useful if you are in the opposite situation and your team is getting butchered, but I don't think I've ever built this ability. Bolt of the Storm should probably be avoided. As far as I can tell you can't control where you go, it has a long cooldown, and its another active to keep track of which can be hard for new players.

Conclusion:
Raynor is my most-played hero. I have tuned his talents over the many games I have played with him. I hope you will have as much fun with him as I have, best of luck. :)
