Hitscan: SoOn and Happy. SoOn is much better Tracer and a good Widow, but Happy is insane on snipers. I'd look out for NlaaeR, Yiangx1aoLG (does he still spell it like this?) and Ivy, too
Flex DPS: GodsB? I haven't seen him much recently, but the alternatives don't seem like a good choice imo. Krystal is probably a safer pick here. The GZ and maybe the DC guys will be good, but idk if they'll be anything outstanding. Maybe Danye could make a mark? Honestly if Atlanta had gotten a flex DPS they'd probably be here alongside Krystal and GodsB, given how they built their roster.
Projectile: SDB, and anyone saying otherwise can stay in bronze. ErsTer will be good, but, c'mon, he's going against Георгий Gushcha's great Genji.
Off Tank: I don't like rating OTs as of late, especially with all the conversation around it. I'd say Jjanu, Daco, and Envy, but my ratings come from when they were on relatively good teams, like 99% of everyone's OT ratings.
Main Tank: I know Pokpo, Bumper, and Guxue are all the rage but wait till you guys meet our lords and saviors LhCloudy and Rio. Idk if they'll be on par with the best of the league but my expectations are pretty high.
Flex Support: Twilight, Lucid, Shu, Neko, WonJaeLee, KodaK. That list is stacked. Toss in Greyy and Bebe (and Gido?) as players with potential.
Main Support: idk what to say besides iDK. Jokes aside, he is probably going to be a highly ranked player in all the league. Slime, Kruise, Masaa, Roki, Chara, and Yveltal, will all be good, too. Slime is insane but I think iDK has an edge over him.
Real quick, because I liked the idea, I'll put the worst player per role as well.
Hitscan: Hooreg and maybe Baconjack.
Flex DPS: Probably Stellar or Stratus (maybe if someone has to role swap they'll be here)
Projectile: Not sure.
OT: againz not sure maybe SanSam?
Flex Support: Hyeonu
Main Support: Hyeonu
