i think group A is the group of upsets because of all the teams being very close in almost ever metric and then billi billi which is the definition of a team that can upset
group B is obviously the group of death with the best or one of the best teams from each region the caliber of each team is insanely high not to mention both teams that won a masters this year are in the same group which is insane to think about
group C i think is the telegraphed group theres like one upset that can happen which is TE beating TLN and if vitality and lev meet it wouldnt be an upset if either of them win in my opinion
group D is the secret group of death with some of the most solid teams from each region G2 has a shout for the best team in americas PRX is one of the most storied orgs in valorant FUT is a top team in EMEA and EDG is making a late resurgence with a win over china (tho minus BLG and FPX thats a pretty low bar)
