Possible to make a new class?

Is it possible to make a new class to the client?.. i guess its possible but how?

If i'm not wrong, the coding needs to be done in your source to get the class working, and you have to add in all the armor, weapons etc. in the client side. So yeah, it takes some time, that's why it's handy to try and make your source work with the latest patch so you have Ninja, which is already another job. And if you don't want ninja, just use other armor pictures for it :D

Nope, its not. Its like trying to create a third socket, not possible unless you do your own client.
Note : I mean that its not possible if your going to do it the correct way.

You can add jobs to professionalname.ini, or change some of the extra ones in there.
