i also use it as a agro grab tool, or to burst my agro for switch, this consern is only tanking wise. the 5 points from improved retaliation will give me 5% hate on GODS buff(witch i can keep active all time), the question is now if i will gain more hate generated by dps from devestate(5% hofs 45% BOA), i doubt it. dps is importent and no class in a raid shud be allowed to slack on it, so wanna be able to deal max dps and tank, this is mainly for t4 encounters.
the spec im fumbling with will be kind of like this.
