2am is not morning what the hell bro

Most of these changes would be because of chemistry/comms stuff like that. I think most orgs/teams/coaches learned from last year that hoping shit will change as the season goes isn't optimal and that if things aren't meshing well in prac/matches they need to make changes as early as possible.
Like for example I remember hearing that the ethan IGL NRG team was broken in spirit before the season even started but they still went forward with it. Hoping for the best won't work out 90% of the time plus there are so few matches

obviously. there are 0 GC teams in challengers
