I'm not at all saying paladins need an enmity boost, but the most curious thing to me in the warrior patch notes was a few abilities getting enmity boosts. To be honest, aside from pickup (because war's mp is a precious commodity so hitting flash more than once blows--like when the healer mistimes a cure), I find holding hate on war easier than paladin, but that might just be me.
We've all seen the exceptionally bad tanks, I'm sure, but enmity boosts won't really help them. Flash with 3x the enmity still = 0 when the paladin isn't casting flash (or the war isn't OP'ing).
The only thing it helps is the undergeared tanks who are really trying, and I approve of this.
