I'd just like to point out that when people say stall is 192301239 and 4 or w/e, we aren't saying it's an argument for why stall is broken. Instead, it really does look like stall is overcentralizing. I dare say the majority of games in the last 4 days have included one player using stall (feel free to correct me). It's really hard to prep for it and very low risk to use (that's where the win rate comes into account).
The argument that people aren't prepping for stall cuz ICT (and by extension supposedly others) didn't expect to play it is BS. Just to dissect that one example: he may not have expected to play it but he still packed Mawile, Zygarde and Greninja which are all mons that put a ton of pressure on stall and even with Rozes' misplays and his own luck he was still at a big disadvantage. I'm not gonna pretend that's the case for all stall vs other playstyle games and I hope the conversation doesn't keep coming back to this game.
Prepping for offense and stall is real hard right now (mostly on the stall end of things)
I don't have PR privilege so I figured here would be a fine place to post.
