never did a 6 man, never will.
no interest at all.
Im just playing ror now because I can do solo RvR with my Chosen (and maybe cool warband with my guild every other day)

Also dont think it would work, I never visited those 6vs6 events, but what I heard is thats the same 2 or 3 teams each time.
Edit: I thought of something, maybe I would do it for the bad ass mounts in the IC, you know what I mean? The full ironclad chaos mounts, dont know what level they are, looks like some elite mounts from live, even if they would just be a skin. But yeah, after I got that I would stop queueing immediatly, so maybe im not what you guys are looking for, I suppose you want constant 6vs6 playerbase development.
