Personally, I like the idea of combining RP and PVP, but in my experience, it has not been fun. Let me put it this way-
I have never seen a post like this:
My Level 30 Sith Lord was dueling with a Level 32 Jedi when a Level 10 Jedi roleplaying a Level 50 Grand Master came out of nowhere and started emote dueling me. Since he was roleplaying a more powerful character I had to let him kill me. Then, when I res, there are three Level 5 Jedi also roleplaying Level 50 Grand Masters waiting for me. I had no choice but to lose the emote duel and let them kill me again.
I know this doesn't happen all of the time, but when it has happened to me, it has never been a "one off." It always seems to happen in long bursts and it just ruins my enjoyment of the game.
