I would make a complete-custom class that can pick any weapon, for any existing class,use any skills of the existing class, but can only use the skills of a cretain class at a time. all stats are averagely balanced between the existing classes. so its not overpowered. I think this would give skilled players, not an advantage over those with big wallets, but even the playing field a little.

will go into more detail if asked.

You mean a Rogue? you aren't by any chance a fan of .hack//GU? xD
