Yea I've love to see them have cool kit utilizing there elements to create supporting effects. I doubt we'll see anything with a lot of ground and/aoe placement since they're trying to phase that out. It would be cool if they had a dance partner effect but like they placed it on a mob/boss and then all their buffing abilities would happen at them and at the boss. So it'd encourage you to position so you were getting the party in one or the other's effect.
Geoknight sounds like Runefencer XD but that'd be cool to get too, I imagine RFC will be the next melee though.
