I, as many others, use TAB set to target nearest enemy.
My problem though is that it often tab around on enemies behind me and as a mele I often loose track or tab around like a madman to get an enemy infront of me.
There should be an option to set it to “Target nearest enemy “IN FRONT” of me”.
TAB targeting has been broken for a couple of expansions now, using it can actually be dangerous. Bu given for how long it’s been practically unusable, I doubt Blizzard will ever fix this.
