I'm going to start up a thread for people who want in on the megabattle, what force they want and to focus the OP on how it's going to go down. There was a lot of great ideas that came from the previous megabattles and well, there can be lots of fun to come from them.
Following the basic plan of the megabattle of order vs. disorder will make teams easier to delineate. I'll throw something up soon to make it more clear and the idea for how we should do this. Bringing order to chaos, I'll be your Abadabadooodon.
