i really think that demon1 isn't a duelist player. even on eg ascent, they would set him up where he could solo lurk mid, pull rotates, and dash out. I feel like lev need to understand that demon1 is best when he doesn't have to contribute to the entry, and can play roles where he is more passive aggressive and isolates.
for example, heres how i would manage comps:
demon1: astra, brim, kj, cypher, chamber, viper (on bind/lotus), iso - roles where he can set util and mainly just play behind the team or by himself
com: breach (without tejo), sova, viper, tejo - roles where he can support the team from behind and play slowly
kingg: breach, kayo, astra, omen, viper, brim - mainly just roles he's comfortable with, allowing him to play with the team and igl well
natank: skye, gekko, kayo, breach, phoenix, vyse, yoru, raze - again comfort roles, allowing him to stick flashes and play what he's good at + also raze
tex: kj, cypher, vyse, chamber, jett (second duelist), viper, iso - basically just roles where he can play individually, similar to demon1
overall stick demon1 on jett for jett maps, and on astra/brim on non jett maps, where he will play senti on omen raze maps (lotus). com, kingg and natank keeps playing what they play, and tex plays a similar role to demon1, except mainly senti
