Raptor should be in a bit longer I think, it won't rotate out until the first 2017 expansion comes out. So I'm thinking 10 months.
Also, I think people should not dismiss Wild as some no mans land.
it goes away along with TGT and BRM whenever it is. First expansion of 2017 could come out earlier than WoG. WoG is clearly behind schedule.
As far as competitive HS goes, wild is irrelevant. Standard is what people will watch and naturally what they will want to play. Wild is for fun.
