I think GK hero has been decided by this point in the month in Open.
wanna do gk cb for fun not to decide who wants hero and what not .
for some ppl open is no fun for whatsoever reason so ppl rather fight the same class they are
Message the GK's in Game, I don't think most of them waste their time on these forums. I just know a lot preferred to do Open, because you faced different classes, and it's a lot more interesting, than CB.
