Guild Wars 2

I can think of a few:
Right click targeting on/off
Right click to attack on/off
Living Story UI on/off
Player titles on/off
Ping Display (if added) on/off
Players name/title (for self) [on/off] [name only] [title only]
LFG icon self/others on/off
Mini guild tags/names on/off
Pet Guild tag on/off [owners name/guild tag]
