Auto Targeting on an ally who buff you? For What?

[Kaedan]

No, in XIV I can't, in other game I can

So yes, you are claiming that in another game, you can target a monster behind you without turning and by just hitting Tab once?

You can in FFXIV too, as long as it's the only monster on the screen (which was a specification you made). So what's your point? And what does this have anything to do with auto targeting a PC who buffs you (only if you have no other target)?
