I think that it would be nice to have a distance tracker somwhere next to the picture of the entity you are targeting; I am aware that there is a red line underneath abilities that is present whenever you are out of range of your target or don’t have anything targeted, but for certain abilities whose effectiveness is determined by range it would be nice to be able to precicely determine the best range for this type of ability (i.e. Ranger’s autoattack for Longbow, or Engineer’s shotgun-type ability for Rifle; the former does more damage the further one is from their target, while the later does more damage the closer one is to their target).
I don’t think this is necessary, or that the above abilities require any improvement, but I feel that it would be a nice feature to add in that would be generally helpful in PvE, especially.
