dead on target.
I didnt ban Deathwing in any of my yesterdays games (whenever I got the leader title, or whtever u call it in ranked) , And im in bronze (just to let you guys know)
I lost 1 game against him, and won 3 games. as Greymane.
And I had no issues at all, even in the one i lost, it was most because we fell behind xp.
Most common explanation for banning deathwing that i got was = All heroes are OP when released, so they should always be banned 
I mean, at least have a go at the hero and see how threatening he is,
