Guild Battles/Tourneys

When a Guild requests a Guild Tournament:

Are the matches simply computer generated? Is there a setting we need?

For example: Our Guild was given an opponent: a Guild so beneath us - that most of them had 'retiring' players; the leaders' teams were also level 3 or 4. Why is this? We really want to play with opponents equal to - or greater than us.

Do you know what's up????
No settings, it's semi-random matchmaking.

How many guild wins do you have? Total fans? I think the game uses those rather than actual team strength to determine what guild you should face.
The opponent selection in guild challenges is based on average fans, there is approximately 20% variance in the number of average fans that the game uses to choose from.
