Don't tame Demon1. Let him use his imagination and create space. He was a beast on EG as they told him just to go kill on Jett.
Don't make Demon1 play raze. His sens is too low and he does not have much experience on raze. No matter what agent, his aim is good enough for 1v3 in most situations.
Victor plays worldclass raze. Let him play raze, while Demon1 plays astra or brim - which we know he is already good. in EG he did not play raze as they had a better raze (jawgemo)
Only on Lev match - COM was a problem as he knows Ethan's calling too well. COM is really good in reading the play. The ascent flank against PRX was insane. I can never forget that.
FNS was the core of NRG/Optic. Not Chet. Do not put the NRG/Optic playstyle for the new set of players. Find your own
Try the PRX method of not having an IGL for a while during scrims. Find out who calls better and who can be the best IGL for the team
If possible, get FNS as the coach or assitant coach
