Here's what I think the best available 100T roster is, I think the flexibility and cohesion between their roles would be a massive advantage allowing them to cook up any unique comps without putting a player on an uncomfortable role and allowing the team to adapt to new metas quicker than other teams. Zellsis and or Zander can igl and help each other call with input from Ethan and Asuna, which takes the pressure off the igl(s), allowing them to focus on fragging out too!
Cryo - Duelist ( Jett, Chamber, Duelist, AWP, can flex Sova / Smokes / Sage )
Ethan - Flash Initiator ( Kayo, Breach, Skye, can flex Sova / Yoru)
Asuna - Scan Initiator / Flex ( Sova, Fade, can flex Kayo / Skye / Raze / Yoru / any agent )
Zander - Controller / Senti ( Astra, Brim, Omen, Viper, Harbor, can flex KJ / Cypher )
Zellsis - sentinel/ flex ( KJ, Cypher, Viper, can flex Kayo / Breach / Phoenix )
Let me know what you think, and what you think the best available 100t roster is! : )
(btw I put in Zander over Bang only because Zander can also play sentinel if Zellsis flexes another roll for a specific comp or game plan, and help call. However, Bang instead of Zander would still be a super strong team if not better, and more likely to happen)
