These probably won't make it onto the upcoming build, but here are three quality of life changes that could improve gameplay.
1. As a player, when targeting enemies with an active ability with a %HP component (e.g. Snuff Out), indicate the enemies that are below the %HP threshold by adding a glowing effect to those enemies.
2. As a player, indicate when passive abilities with activation conditions (e.g. Mob Cover) are active by making the ability icons glow (by glow, I mean the glowing effect that appears on the inventory icon when you get a new item in your inventory). Or indicate when they aren't active by greying the ability icons out or putting X's over them.
3. As a player, when an ability comes off cooldown, make the ability icon glow.
