First of all its great to see such s postive response. After further consideration I believe that 3 vs 3 tournament is probably the best route to go.
As a side note i was thinking maybe also running a last man/woman standing competion in Gurubashi Arena. Use to do this for fun back in tbc with my old guild. Again I would be more than willing to provide cash prize for the winner.
Anyway still got alot issues to iron out before running this, so pls feel free to post an comments or suggestions, I need all the help i can get
