Crit Ice Shot Deadeye. Help needed

https://poe.ninja/poe2/profile/Siz0u-4969/runesofaldur/character/AnotherLAnotherDeadeye
Having trouble clearing t15 comfortably with this build. 36% crit on ice shot in tooltip in hideout. It takes 2-3 shots to kill basic white mobs if doesn't crit. Extra as cold dmg from mark is always up. I basically have damage everywhere, and it just doesn't feel smooth to play. Any advice?
