I will say from the start I also considered putting this in suggestions so if that's where this belongs then so be it.

The radius for gathering from resource mobs is less than the radius for looting and for combat. This means when I kill mobs like mith golems, I can melee the thing, pick it's pockets when it's dead, but then I have to move in to gather ore with my pick. It's particularly annoying when the thing dies right on top of me and it's body is actually covering my toon, but it's still telling me i'm not close enough to gather.
