IGLs kinda have to be developed in T1 imo. Cant only rely on T2 like with aimers. Boo, fallin and cender have stepped up nicely so far and are improving.
I think Boo is the clear favorite, since he got his team to the finals of both masters and (I think) kickoff + split 1. (I didnt realize this is a T2 post my fault, my fault)
