I have been leveling an Orc Warrior on the Alexstraza server with my sister. Well, she is basically running me through shit. Now I remember why. Tanking at that level (22) is terrible. Rage generation is bad, and you dont have taunt yet. Or anything else that is fun.
I got into a run in BFD, an istance that I am not at all familiar with. Tanking was non existent for the most part. I was pretty much an aggro merry-g0-round. And you know what? It didnt really matter. Nobody was in serious danger of dying until we pulled the entire room on the Murloc boss.
At level 22, there is no such thing as spamming something. I heroic strike once, and my rage is gone, gone, gone. If you are going to tank anything below level 40ish, I would suggest just going DPS and whacking stuff with a two hander. I dont even have defensive stance yet.
I love tanking. I LOVE warrior tanking. I just hate tanking as a lowbie.
