"Modern day characteristics" refers to what we use to decide what bans Pokemon now. Not that hard to understand.
I'm not claiming to have extensive knowledge of the GSC metagame, but I've heard some of these arguments come and go and they actually seem theoretically sound. I can definitely see Celebi being banned for being a stalling whore, since most of the things that beat it now are simply not applicable.
Anyway, I'm going to end the argument here since I'm clearly out of my element. For future references, just tone it down a notch. There's being militant, then there's being annoying. Just saying.
