Associations one-team leagues/events

I came back after 7 or so months, so I don't know if it happened or not yet.

It would be cool if all 6 (or 5 or 4 anyway, depending the size of the association) members of an association get together and make a combined "dream team", consisting of every member's best players and maybe the captain of the association takes control of the team. Every member can watch the game of course and everyone gets rewards in the end.

It would be association battles with a tournament of perhaps 14 teams. More like an event. I think you get the idea.
