IK people keep saying drop people for an IGL but I'm still struggling in my head to think of who they could pick up to IGL. I completely agree but it def isn't as easy as people make it seem like it is. Off the top of my head they could grab
Stellar(former IGL of LG, LG never had top tier strats but it's better than nothing and has T1 experience)
Iyen/Stronglegs(IGL's for the best T2 teams, neither would prob leave their team tho)
Poised/Oderus(The two emerging teams from this most recent qualifier, I'm a big fan of both so these two would be my favorites
Rossy(prob unlikely but IMT does like to sell players)
Payen/Dcop/Valyn/Ryann/dsr (all players that either aren't t1 level or don't have enough IGL experience IMO)
So I think if they add Levi and dropped Subroza/Hazed (IDC who but I'd honestly prefer Subroza at this point) for one of Stellar,Poised or Oderus I'd say it's an improvement on the roster.
