Players that will fall off without a doubt- Most of the NA players like tex, dicey, bdog. Optic will see a heavy toll, esp when they will have to change up their comps, it wont be the same optic we have seen before. Internationally tacolilla, a lot of the SEA chamber 1 tricks.
Teams that will thrive on this nerf- 100T, Guard, Acend, Liquid, M3C. These teams were always lacking on picking up the chamber, and their strats are revolved around non-chamber comps, no wonder we didn't see these teams anymore. Guard fell off hard because they tried to fit jett demon sayaplayer on chamber, which clearly didnt work out.
Overall there will be a significant drop in the quality of NA teams, which already look horrendous and with their best team Optic taking a big toll, it will just be a repeat of last year, where EMEA and APAC teams will dominate champions this time, the only difference is APAC and EMEA will be a lot closer than the blowouts last year. LOUD should also be doing well, they are not chamber focused and their star players are excellent on Killjoy and other agents.
