Obviously who's going to Champs isn't guaranteed (at least for the most part), but given what we know now who can realistically win??
These are just based on my opinions, and my knowledge is heavily Americas biased cause I've watched the most of those matches.
Frontrunners: TH, SEN, GENG, PRX
Contenders: G2, 100T (if in Stage 1/Shanghai form) FUT, FNC
Need an insane run: DRX, LEV
Either already are in or probably will make champs, but can't win IMO: 100T if they play like they did in Stage 2, Talon, KC, EDG, FPX + whatever other CN teams make it
Also whyyyy are we back to doing a group stage for Champs???? The Swiss seemed to be so much better from my perspective
