I think it would be really fun to play the following modes.......
All Mid Wars (This is were all 10 players get the same characters and you all go up the mid lane)
This way were are all in a good position to learn something new E.g character/role/etc.
We could have more fun this way. Just an Idea.
Anyway How are we going to pick the teams? first 5 to turn up or something more constructive like picking names out of a hat?
