I'm currently of the mind that he can exist and that it does nothing to me, for me, or against me. He just is, which is a big problem with the character in general. He's so flat and that leads to him being used for whatever role might fit him best (whining about Barry, being Slade's lackey/flunky, questioning Damian's leadership, whatever the writer needs) and that's just... so unattractive to me. He needs some purpose that sets him apart from Barry, Wally, and Bart and he needs a name change that makes him more identifiable. When you say Wallace West people are gonna think the redheaded Wally, not this kid, so why not call him... Ace? Or something? And set him up as the cool, edgy Flash, equivalent to Jason Todd. It'd make him unique and dare I say maybe even interesting.
