I recently managed to level my Warrior alt to 80. So far, I'm absolutely loving Prot's playstyle. It's in some ways reminiscent of my lock's many specs that rely on priority systems, and as such, I wouldn't be surprised if Prot warriors had the most intensive, fun tanking rotations in the game.
I believe I've mastered single target threat generation; one of my favorite things about the class is its reliance on skill, and that if you have it, you can manage to keep threat on people decked out in very relatively high end gear. However, I've stumbled upon some conflicting views on AoE tanking. I already prioritize TC>SW>normal rotation whilst switching targets, but I'm unsure of whether to be spamming Heroic Strike or Cleave.
Tankspot's guide to Prot Warriors gives a very indepth guide on threat priorities, and according to them, Heroic Strike is far more valuable even when pulling multiple mobs, due to it's relatively high threat production and Cleave's mechanics (which divides threat among the targets). But when Googling "Cleave vs. Heroic Strike", it seems that most people favor Cleave, because it still does generate some threat on multiple targets. Elitist Jerks also favors Cleave, although it gives no explanation as to why.
Which ability do you suggest I use, and why? (I may as well set up a poll, in case this generates some discussion) Thanks for your time
