well just a suggestion i Think you should make the Party boxes Minimizeable like Click on the Party box thingy and poof it hides your team members as well as smaller enemy boxes on the top left of the screen right over the party box.
now what does this accomplish well i usually main a manual aiming class so when i end up having to move my mouse cursor alot or my enemy moves to the top or left borders i cant hit them because their UI bars and what not are in the way thus making my skills be casted right on my legs thus being wasted giving unnesary cooldowns.
