I'm starting to think this is like a light version of Mario vs. Samus. People too hung up on Red's past performances to see the logic of the matter. I'm really surprised the debate is their match vs. Luigi/Waluigi.
Could be me with the crazy logic though! Just don't get this attitude that they'll be weak or whatever. For reference I never put much stock in Red, iirc, but Red/Blue is going to be strong.
