Handy guide.

So asking as a WAR beginner, when I get to the point of trash pulling in dungeons do I pull in Defiance and stay there? Or switch to Deliverance and do some AoEs then pop back into tank stance?

Same with bosses, full time tank stance or do most WARs just stay in Deliverance and pray the healer is good? I've seen so many tanks do this in 70 dungeons.
