Erm, people with magic can carry a sword and armor just like everyone else? For a long while now we've "rped" that a mage's sword/armor they carry is to represent their magical fighting abilities.
I mean they can't use "fire" or whatever in pvp, just normal weapons. Which is originally why I thought the idea was good, it could make pvp easier for mages, who want to use their magic to fight instead. But lets stop, I don't like arguing :P
It would not make Pvp easier for mages. As I said, a plugin isn't going to make you better or worse at Pvp. The only thing a magic plugin does is add 'cool' factor because you can use actual spell particles instead of normal weapons to represent magic.
