Did notice that when solo you can only dispel shields off yourself in combat but not curses, and when in group you can dispel curses but not shields off of yourself when in combat.
This was previously mentioned in another bug thread (wasn't sure if was confirmed bug or if this is intentional); however, to add to this I did notice that if you are in a group regardless if other char is in combat cloud with you or not does not matter to the rules above they still apply, so for pvp it is an advantage currently to be in a group even if your group members are not in combat cloud with you.
Also when in or out of combat missile resist will not get dispelled like the other buffs regardless of in or out of combat also regardless if in group with other players or not
