I bought the Enhanced Edition, and it had dividers for heroes, villains, and environments that weren't in it; then I bought the Rook City and Infernal Relics box, and that had the dividers again. Both also had a divider for Unity and Ambuscade, which came with their own dividers as well. So I have three copies of those two, and two copies of everything in the IR box. Being the compulsive type, I decided I wanted to use these extra dividers, so I started putting a divider on each side of the appropriate decks, so that I could see them from either side. And I decided that I liked this system, so now I would like to get duplicates of the dividers I don't already have myself duplicates of. If I just got a complete set of dividers, I'd be back where I started; is there a way that I can just get extra dividers for EE, Shattered Timelines and the mini-expansions that came with it, Vengeance, and eventually WOTC and its mini-expansions? (I'm still stuck with the triplicates of Uni and Amby, but I can live with that much redundancy; it was just the big stack of RC/IR stuff that was too much for me to tolerate.)
