Currently the issue to me is you have Asuna on Jett being the primary operator player (a role he statistically & historically does worse on compared to his Raze/Reyna) or Ethan on Chamber (a role I think he is good at but he says he does not like apparently) and then Hiko picking up Sova (a role he himself said he is too passive for and is trying to move away from) so in that situation the core three are all on roles where they either don’t shine or are uncomfortable.
I think the roles need to be...
Asuna - Flex/Secondary Duelist...His rifling is too good to put him on the op + he statistically does way better on Raze/Reyna. I am not sure how he would do on Kay/O or Skye, but he has played those roles on some random team during the offseason last year.
Ethan - Sova/Secondary Flex/IGL...his sova is really good. Its an agent he is comfortable on. Its a role not many outside of Crashies and Trent are incredible at, so he fills that for 100T. Plus he has the ability to switch off on maps like fracture and split.
jcStani - Controller/Secondary IGL...He is a really smart player with great aim, comms, and ideas. He has lead teams in the past, so he is a great asset for Ethan as he learns the IGL role. Plus he is a solid smokes anchor.
-bang (just because of role overlap...if he wanted to pickup the sentinel role it could make sense, but it would overlap with Asuna in this idea of the roster)
-hiko (the way the current team is again there are way too many role overlaps, and they aren't solid enough to justify.)
+some cracked operator player that has flex from Jett to Chamber (Kanpeki?? Will?? Mina??)
+a solid anchor/sentinel player even though NA doesn't have any crazy sentinel players right now.
+sgares who can lead the team in good fundamentals (spacing, lurks, timings, and things like that) plus he has been an IGL of top tier CS teams, so he can help Ethan grow in that role.
