what happened is that nearly every team in APAC is at least good and so both APAC and CN - Who can scrim each other - Now have exceptional access to all the on-level scrim partners they could ever ask for (despite sharing drama cutting a few out) meaning excellent practice and elevating the entirety of the two regions.
EMEA rosters all have fairly clear flaws that the orgs KEEP IGNORING year on year except FNC and post-toronto, likely TL too now thanks to +Penny and the fire that lit under Serial's ass. TH, BBL need real performance coaches who actually do the job so the players have the mental to stop fucking inting, KC needs to stop pretending that midrounding isn't important (Both Engh and Saadhak are great at making and adapting set plays but they need a sacy-like second caller because holy shit they have no clue midround), VIT just needs a real fucking IGL instead of a bum 1 trick duelist who refuses to play duelist and the rest need coaches that aren't pissing away their talented rosters.
AMER teams besides SEN are either outright dogshit OR just refuse to experiment with shit ever OR, MORE COMMONLY, both. They had some of the most prac time and yet G2's meta read post Tejo and Breach nerf is "lol same comps but sova/fade" as if breach was doing well at all prior to Tejo. SEN at least practices against their Academy enough to take and adapt other team's ideas well.
