This is my raid spec (and pretty much what I run around with doing instances atm). I just betrayed from a guard a week or two ago so I'm revising as I go along.
I'm the MT, so I try and focus on anything that gives me hate/defense/healing. I'm not 250 yet because as a guard everything over 227aa's was pretty useless and he was boring as all hell to play, so I have alts. The zerker aa's are quite good however and I should be at 250 in the week.
So I went 10 in Executions Anger and 5 in Gladiator's revenge in the warrior tree. I figured I would rather have an extra 15% base to taunts (30% base total) then 1% worth of uncontested block (around 2.5% total), however you can go either way on this.
In the Zerker tree with the last 5 points I'm going to add 1 to Insolent Cry, 2 to ward of rage, and then 2 to bath of blood.
