You guys want a 6v6 ladder on top of the 6v6 league? Train and I were talking about that last night and almost think that's overkill and most teams would be too busy.
Ok, the concept behind this is to allow teams to play matches to practice for the ladder. Instead of having to search out scrims they can arrange one on the ladder format and it will allow team(s) that don't know if they want to play in the league a chance to see the setup and play some games. It is also good for the between times from one season to the next, as well as, testing of new map(s).
