i would drop vakk and bring bonecold back if it was possible but the changes are made and i believe they will stick together at least this year.
i am not here to talk shit about 100T but if i know a little bit about Nadeshot he is not happy about 100T not qualifying to Masters. Ofc making changes is not the only option but i would try to get an operator player + igl (don't want to be harsh on stellar but igl makes you win or lose the game)
i was supporting 100T but they failed to qualify which means they are not good enough, i wouldn't drop Will and stellar directly but if they also fail to qualify for Champions...
