I don't mind where we play, the result will be at the same time as guild sign up.

5 will result in all guild halls being used at random, and by this I mean a chance for all 10 guild halls.

4 will result in all matches taking place in 1 guild hall, but changing each week and picked at random, so 4 guild halls will be used, 1 for each week.

3 will result in each team who enter having an equal chance to play in there guild hall.
Example.
If Guild pants play Guild socks the guild hall will be pants

If Guild socks play Guild Pants, the guild hall will be socks

2. Will result in all guilds playing 'away.'  
In theory, no team will have an advantage as we will use a guild hall of a guild that did not enter the cup, although this is a bit cheeky, i'm sure they'll never notice.

1. will result in the sup cup being in the sup guild, duh!

I'd let this depend on or influence the way the eventual matches will be played...

Option 3 sounds good to me, if we'd play best of three or so.
Other options sound good to me if we'd play just 1 match each...

Maybe we can just let this be decided game per game, and if there would be no agreement between two guilds, fight in a gh of a guild that doesn't participate in that particular fight.

CLOSED.
Winner
