I say go for it.

As someone who really only plays Wushu, Lenshu, Ninjitsu and maybe a few other modes that aren't in the official servers, I think it would encourage me to play more. Plus it would keep the game fresh, maybe do one room where the mode changes on a frequent basis, as Dika said (though I haven't played a fraction of them) there are a lot of game modes that get passed over because they aren't one of the modes in the main servers.

We CAN make our own servers, but I think it would be nice if maybe the promo team had a room they set up every week/bi-week/or month. It would spice things up, for sure.
