[@Lord Wraith] that sounds acceptable to me. Also the idea of keeping supporting cast to actual close legacies rather than far off distant ones? As you said it got kinda silly.

I have this idea of allowing stories happening in the past, present and future meaning that you can have your solo Batman but also have stories with Nightwing or Robin without messing up the Batman player's plans. If that player wants they could guest write any needed interaction with Batman or simply allow the other player to do so themselves so long as that player doesn't go overboard (ie including Batman in every post). 

My other thing is, there won't be supporting casts on the proposal but I'd be okay with people laying claim to characters they need for their current arc. So if you're doing Flash versus Captain Cold as your first arc, I'd be okay with denying a Captain Cold app but only so long as that arc is running. When your arc has concluded, I'd expect the character to be free for a player to apply for.
