Another important option that needs to be addressed with targeting is hopefully adding the feature of targeting the NEAREST target, not all targets in the vicinity. It's frustrating coming into a dungeon room full of monsters, tab targetting and accidently missing the monster I'm trying to tab target... then I have to tab target through everything else in the room to get back to my target that I missed originally.
FIX:
Allow us two keybind options in the user interface area: Target Next Target, and Target Nearest Target
Another problem is I still feel that the indication that something is targeted in the game is still very shallow. In the heat of combat with lots of players and enemies, it's so frustratingly hard to see if I have my proper target selected.
FIX: Add some sort of circle under the monster, similar to most modern target-type games, so we can see a more clear indication that we have selected the proper monster. Another reccomendation is to add the ability to toggle Nameplates. For those of you that don't know what nameplates are:

See how easy it is to identify that target is selected? I'm not saying it HAS to be like that, but look how easy it is to see if the target is selected or not.
