I tested Gunslingers on diffrent servers, and they all worked correctly, I'm sure it wouldn't be that hard to introduce Gunners (Ninjas on the other hand...).
Lots of nice little things coming along, good luck Pan and break a leg (literaly, so you will be fixed in front of your comp, forced to commit 23h per day on the server.. 1h to sleep/eat).
