I’m sure others have said this before myself, but wanted to share more feedback from my personal experience.
1.) Make PvE mobs have a colored outline that makes them visible through other players.
It is so hard to see what I’m aiming at in this game while melee players are stacked up body blocking each other. I even have player nameplates reduced to only show 2 at a time.
2.) Add an option to change your crosshair color.
