I would like to go on a long shot here and say pack tactics is the new coming ...
but I see it as a block beater ... and no , not in a feral deck ... in a resto rush-midrange deck (yeah , the new resto talent is at least try worthy , and I really can see it shine )
all those allies beefed up to more then 2 health , they AoE you for 2 and then another 2 and you flip your hero (dorn the tranquil ) in response
and not to forget tigers fury +rak goes a long way too
I would certainly love to see a pack tactics deck (block or constructed format )
so my vote goes to DRUID !!! naturaly
