I think realistically, keeping asuna is probably going to happen, mostly because he's pretty good on the raze and plays flash well (also never put him on neon ever again. If we're looking at stage 2 performance, he's only dropped stinkers on the neon. Every other agent, he's been either really good or just average on it. Also, I feel like he'd perform better if they didn't just throw him into situations). I do agree that dropping Kess is probably good though. What I think is best:
1) Drop Kess. I think he has a high ceiling, but he's just not right for the roles tbh.
2) Pick up Penny. He's proven to be very, very good on the duelist. Additionally, it opens the room for double duelist. I think koalanoob is a good option, but penny has been lowk a solo carry on apeks so.
3) I agree with your additions to the coaching staff, except maybe also keep zikz at least as an assistant coach.
4) Agree on the cryo being full time senti, but lowk run double duelist on jett maps and also slap my guy on chamber when possible
Roles being:
Zander on smokes, asuna as the flash initiator/flex, cryo on senti (and jett on jett maps), eeiu on scan, penny on main duelist
