New Elite Capture Skills
would be nice to have a skill that learn after completing a monster arena that is a real challenge to beat. That would promote it risk vs reward. Or how about a challenge where u place your one skill you dont like (unlocked needed) for a chance to obtain a different skill. If you lose you only lose the skill point used to unlocked it and it becomes locked. We do have never ending level to gain skill pts. soooo why not
I like the idea of an arena for a skill. It would be sort of the the Norn Fighting Tournament in GW1. Not sure about swapping out skills though. That may be asking for too much customization.
