If Yasuo is going to have the e damage removed, his crit reduction needs to be lowered on his q
right now his q have 25% crit reduction which means that late game it does less than an auto attack
yasuo's e deals a significant amount of his early game damage in dueling and that can't be removed without compensation in other areas
something like his e having a much lower cooldown and lockout time or having higher range would help, but really yasuo's passive crit reduction needs to be lowered to 5% or removed entirely for him to still be viable. his q could have the 10% crit reduction
