I also remember reading somewhere that they planned to improve it, but in the meantime, you can kinda fix it yourself with target filtering.

If you go to Character Config > Filters, uncheck all of the boxes for the weapon drawn section except for "Aggroing Enemies". Next, change the Tab keybind to System > "Move Cursor/Target Cursor Right/Left" (either one will work).



Once you have it set like this, pressing tab while you have your weapon drawn will move your target cursor only among aggroing enemies. Granted, this doesn't actually target the enemies, but using an ability will target them.
