Will ninja be STR or DEX based or will there be a new attribute?

[Urielparadox]

Drg and monk only shair accesories. If they make dex effect physical dps, they don't just have to change the tool tip they have to change the stat and how it works, how damage is calculated using dex for ninja would be different then how it is for bard, since bard is designed with the singing punishment in mind. It much easier on programming to just make it use str.
