I don't know if this is a Pokemon Online twist or not, but, I was doing a generation 1 battle and Wrap was using the same mechanics as the future gens. In Generation 1, Wrap was like a freeze or a sleep that hurt you each turn and kept you from attacking. It'd be cool if PO could implement it, but if you want to keep it out, who am I to stop you?
I play Stadium, and, I prefer Wrap do not work. I prefer the possibility that wrap worked in true RBY, and not in Stadium. If wrap worked in Stadium, dragonite will be a god.
I hate wrap in RBY. And Clamp. Get a Cloyster out there and no-one can stop it... So says my memories with my brother...
Doesn't matter if you hate it or not. It's part of the game regardless. Anyways its bugged on PO, and will likely be fixed next update, so enjoy while you can.
Starmie, Alakazam (Zam not 100% but still). And clamp runs out of PP pretty quickly by just switching between Chansey/Starmie/Exeggutor/Lapras. To be honest, any attempt to officially ban something in rby nowadays will just not work out. Although Wrap is officially banned in rby2k10, it remains unbanned or unspokenly/unofficially banned in the typical random netbattle match.
Why would it be banned before it's even correct in the metagame? Wait until it's fixed before you start talking about banning it.
