I'd really like to see more 'test' series involving Provincial teams rather than the current format. I don't really know how it could be implemented though.
I'd like to see in the future the ability to loan a certain number of players for a certain number of time. It would make things more interesting and might bring balance to the ALC teams. The loan would be void as soon as that player is required by the team who own them. It would allow for more interaction between teams. Might be hard to implement and not necessary but it is an idea to change things around.
