Also, the paid Custom Arena should have the ability to do the same kind of persistent AI-only cyclic scheduled missions like the Mission Arena so players could create their own AI augmented worlds like I did for the WW1WF.
WWII Eastern Front? Battle of Britain? WWII Pacific Front? Mighty Eighth? Operation Sea Lion? Invasion USA? Invasion of Japan? how cool would it be to have a custom arena running 24/7 with 400 AI planes fighting out a Battle of Britain for you to join in any time you felt like it?
I don't think you can do that current Custom Arenas. For a non-melee arena that may not often be populated, I think it is vital to use AI-augmentation so that if a single player goes in there, they can have fun doing stuff even if no one else is around. (Heck, I think the Melee could benefit from a little of that, but it would be too large a cultural leap for veteran players to accept. Not worth the shrieking you would have to put up with.)
