I think we're gonna have to exercise patience with DC, even if they do put a real, honest effort into fixing Wally.
Assuming that DC wants to use Wally well and continue building on him, then we're in new territory. Barry has been back for ages but Wally has never actually been treated like a viable, important part of the DC pantheon while his uncle is still running around. Wally can't just go back to doing what he was before Barry's return; it'll just be redundant as hell (it might sell okay, but I don't know how many people would truly be satisfied). They're gonna have to try out different roles and see what works.
Seems like right now they're pointing him towards being a multiversal character, which I'm not against seeing. But we'll see how it goes....if DC really does try to do right by him now that Didio's out.
I honestly have higher hopes for Nightwing than I do Wally.
