after some recent upgrades i am able to regem some pieces away from straight +stam to help round out my block / avoidance kit. what gems should i be looking for to fill those newly available slots? i have enough badges to buy the old badge +block cloak or one other piece of gear. gear wise i have just about everything thats available pre-gorefiend / azgalor, we havent hit either of them yet.

this should be the block kit:
The World of Warcraft Armory
