I spend more time fighting the targeting UI than I do fighting opponents

And what if u want to heal some poor guy fighting who is not in your group?
Pls tell me cant wait to hear your answer!

Target of Target will help in some ways.

It would fix or alleviate the problem with tab-target, though. Or the inability to target by clicking on nameplates/healthbars above character's heads.

But it won't be truly useful to healers until mouse-over targeting comes.

You either have no clue what you're talking about, or you are completely confused by the complaints in this thread.

Yes, "target next enemy" "works" in the sense that it targets "a next enemy". It does not behave intuitively, however, because it seems as though it targets enemies in order of proximity, regardless of character facing.

Play Warcraft for two minutes. Hit tab a few times. See how intuitive it feels? Your tab target preferentially targets enemies you are FACING. Not enemies that are behind you, or off to some side hidden behind a pillar.

Also note that you can target nameplate/healthbars in WoW. And that targeting boxes are much larger (and more intuitive).

Put another way: I never once in the four or five years of playing WoW *ever* heard someone talk about having to rebind "tab" to "target nearest enemy". I never felt like targeting opponents was a chore while playing Battlegrounds, and I never screamed in rage as my tab button targeted a guy that was 10 yards behind me instead of a guy that was 11 yards directly in front of me.

Hell, even modifier macros would be amazing, for things like self-target and focus-target.

Especially as a healer, it is insanely difficult to target people that need heals. Since you can't click on nameplates (why?) and tab (or ctrl-tab for friendlies) is ridiculously unreliable and has the great habit of targeting people BEHIND YOU, it really seems like this game's PvP is as much about trying to target the right people as it is actually fighting.

And obviously, I would much prefer to actually play against opponents instead of fighting with the UI.

This game very, very badly needs an improved tab-target system (no, 'target nearest enemy' is not sufficient) and badly needs the ability to target people by health bars / nameplates.

They have keybind options for those in game already.
