What I don't get, and pardon me for sounding like another frustrated member, is you have 8+ years of MMO experience under your belt, and you [insert word here] this kind of backward UI.

1. Number the members
Reflex, players can immediately associate the number next to the party member, with the function key tied to that member.
2. More clear, brighter indication of the member that's selected.
Please recognize that in the heat of some battles, players move around, and for a supporting role it becomes primarily a UI-based system. No longer am I looking to see who i'm targeting, I rely on my UI to indicate everything. And yes, sub-targeting doesn't highlight members in party UI
3. Add me into the party list

Credit should go where it's due, i absolutely LOVE that I can move UI elements around my screen, and adjust them to size of my liking. This is a HUGE thank you
