Frankly, I would much rather have Vibe back over Donna or Wally. Not because I hate either, I just would rather see him get the developement they've already recieved. And in Donna's case, recieved and recieved and recieved and recieved. If she was a VHS tape she's be nothing but static by now with holes worn through.
As for Vibe, if he's handled properly, fine. Hope a rebooted Vibe is written better than a rebooted Jaime Reyes. Poor Jaime.
Looking forward to the Vibe reboot. Minus the 80's stereotypes.
I do want Donna and Wally to return but i do want them to stand out rather than fill the role of WW and Flash-lite.
