In the times its taken to get to and kill HC Garrosh (10man) I only just gained my 2 set (And i'm pretty sure i coined the chest), Because Paladin tier is the least dropped one and never drops, And on the occasionally time it does, I've passed it to our lock or priest because i can make do with haste gear wheras the DPS need the setbonus's for a bigger overall raid increase. I just haven't bothered with the 4set (and tbh i'm not all that sure my 2set is awesome, I just have the chest/hands because they are greatly itemized) Maybe while farming everything, If any spare tokens of our tier drop ill get to try it out for giggles.
