Rexxar is an new hero whom is deemed as a ranged warrior. Has plenty of cc and a pretty decent health pool split between him and Misha. His talants can not only enhance these abilities even more, but can gain the ability to flare (for vision and stealth) and can do more dmg to structures, minions/camps.

Tier 1: Hunter-Gatherer
I feel that this or Grizzled Bear is the way to go. Rexxar is sorta weak if he is caught off guard and having the extra regen helps out alot to get back into the fight. Luckly Misha can pick them up for you, so you can retrieve them without worry.

Tier 2: Easy Prey
I love Easy Prey, you can easily solo merc camps with this and clear lanes even faster. If you are still having issues with surviving, taking Hungry Bear is not half bad either.

Tier 3: Aspect of the Beast
Aspect of the Beast is my favorite talent in this tier, basically this is a mini Battle Momentum for Misha's charge. This we help keep the pressure on heroes and is also good for siege camps.

Tier 4: Bestial Wrath
I prefer this heroic over the boars cause in team fight Misha can help not only stun the heroes but also wreck them as well.

Tier 5: Bear Necessities
Bear Necessities is another good talent to help you solo not only camps but the bosses as well. Also helps if you missed a hero by mistake, they jumped out of the way or even help close the cap with 2 giant bear jumps WOHOOOO!!!!

Tier 6: Aspect of the Hawk
Also Critical Care is a good choice if you need Misha to heal more. However Hawk is what I prefer due to the fact that it gives a decent AS boost to you so not only is Misha wrecking their face but you just slowed them and hitting them even faster than before.

Tier 7: Spirit Bond
This or Frenzy, I prefer bond due the fact it gives you healing and increases Misha's ulti duration even more.
