Dual wielders at chinese can be specialised at crit, hit rate, dmg.
You can make skills like Hit rate increase, crit increase, phy attack power increase and also some skills which can stun, bleed and so on.
Also you can make something like "Iron Skil"- Phy and Mag Defence increase as passive so the complete class would have same style as any other chinese style.
Sure you have to setup the skills correctly so it will not get over powered.
