I want to be able to duel my companion to try out my abilities, combos, etc. Sometimes you cant find a person to duel with and I believe that it would be awesome to be able to duel your own companion.
Also I believe it would be great if there was a search engine that would let you queue for Operation or Flashpoint Missions you have. It is sometimes hard to find a group and would be awesome if I could just queue for the Operation or Flashpoint while I do my quests.
