Envy(If they don't qual to Berlin and want to make a change): -Mummay +Yay(If he's still available)
FaZe(if they don't do good at Playoffs): -Rawkus +Temperature/Critical/Derrek/Meeeeester Juan
C9B: move poiz to the inactive roster +Yay(Poiz is a great player but it's like a 100T Ethan situation where the opportunity is too good to pass up on)
Gen.G: -MkaeL +Yay/Thwifo/c4Lypso/Temperature/KOLER/Oderus/Bjor(Temperature would be the ideal fit but all of these players are great and Yay would be the best pickup if NaturE, Koosta and Shawn could take over MkaeL's role)
T1(or they could give the team some more time with Curry IGLing): Just get Autimatic and Curry some more help. Obviously they gotta keep Brax so maybe drop Ska and/or Dawn and get some good replacements(maybe someone from a smaller org that's still really good like Andersin or Oderus)
NRG(either try eeiu IGLing and see how that works or make some changes): If they can, they should definitely get Yay and replace Tex(even though I still think Tex is good, once again Yay is too good to pass up on and reconnecting him with Android would be cool), but if not I think they definitely should keep eeiu, Android and maybe tex and either drop Wedid and s0m or put Wedid on viper/astra and maybe omen and brim and pick up someone to play cypher/brim/omen. I would rather see Wedid on Astra than s0m and idk why they have Android on viper and not Wedid. I'd like to see Android on kayo/skye, Tex on jett/raze(unless they pick up Yay), Wedid on astra/viper, eeiu on sova/skye and someone like Temperature, c4Lypso or Thwifo on Cypher and smokes.
Andbox, Complexity and EG are all 3 other big orgs that need changes but they clearly don't care enough about their Valorant teams to invest in making good changes or they can't afford to make big changes.
