I honestly think I may drop Swamp Thing completely which upsets me. He just looks a little to risky to me. His vine grab that goes across screen needs to be done short, medium,far or some fourth distance and you whiff if you gauge it wrong.
My other possibility is Harley. Shes like a sexy retarded version of Erron Black with puppies. With her trait being a standard now she could be very viable so I am thinking of co-maining her with Robin. From videos I have seen she fills in his gaps.
