Are you suggesting we can have alts that are specifically just for the Arenas? I could get down with that, it would be a good place to try out some other class combos. If this thing really takes off, it could provide a whole different style of play to the server and attract a more diverse playerbase!
I will take this to the team, but the concerns with alts is there interaction with OOC knowledge/actions and other main characters. For me I happy for you to build a character that is only an Arena Fighter but I wonder what would be the benefit of loot and such? a different playing style .. maybe.
