Arena attempts

[S0ulpuncH]

Figured this might have been suggested a thousand times before, but after a quick search i didn't find anything. Anyway, I wanted to suggest a way for players to be able to run Team Arena after their attempts are all gone. I know this can cause issues with 1 player feeling like they have to help their entire guild but it would be really beneficial since it always seems that 1 or 2 people end up being the only people with arena attempts left and they cannot finish it. I guess the same goes for the Team Dungeon attempts as well.
