UI Suggestion - Auto Targeting!!!!!

One of the things that I've encountered during running a dungeon (or anything else) with another person is that little problem of targeting.  Oh I can target an opponent without a problem,.....on my own....But with a group it's a little bit difficult for me for some odd reason.  I know this might be late in the game to suggest this idea for the UI Hub.....but what about having an Auto Target mode while in combat???  I mean just think of it.  People don't have to point and click on a target if they don't have a fancy schmancy programmable gaming keyboard (like me).  Many other MMOs have this feature.  Why can't we??  I know,....it's extra amounts of programming and coding and all that sort of stuff.   But in the long run it would something that would benefit players across the board.
