While their performance in the online tournaments aren't consistent they still have a good chance since the next TI is a year away and now is a good time for them to rebuild while ana is on a break.
They really need Ana so badly. Still no one can replaced ANA as pos.1 even Sumail and worst MidOne. Mid One pos.1 is very unstable and he was always left behind by opponent pos.1, He surely not fitted anymore for Pos. 1. Saksa is doing great as replacement to jerAx as pos.4 although JerAx is the best. Saksa gameplay is very consistent and very stylish. I hope Ana will really back on TI or else we can see an early exit for OG on TI.
Ceb already talked about this but he never really stated an obvious answer. They let go Sumail because of this.

Sumail is a better player and I guess without this pandemic, they will be trampling the offline tournaments with Ana just standing and watching at their sides.
