The enmity increase on Defiance is likely there to offset the increased enmity generated by healers when a 2.1 warrior is tanking. The overpower enmity modifier being increased as well is weird, though. Paladin will almost definitely get some tweaks and changes in 2.1, as every class will. Even if Awareness was working properly, it's a really bad skill, so I could see them changing that. They could also make adjustments to our cross-class skills and some of our mediocre native abilities. I could see Riot Blade, Shield Swipe, and Cover all getting changed a bit.
