So Rogues are gonna replace retri paladins. With the change to JotW, BattleShout=BoM, and this one I don't think Retri will have a slot in raids.Assassination
Master Poisoner moved to Tier 9, no longer increases chance to hit with poison attacks, now increases the critical hit chance of all attacks made against any target you have poisoned by 1/2/3% and reduces the duration of all Poison effects applied to you by 17/34/50%. (This does not stack with the Paladin talent Heart of the Crusader.)
I know that is Beta and things could change, but we paladins know how Blizz work with us in Betas.
