Assassin's pure technical flow, you are rich enough, then play assassin. Wu Ji is a little blind with your good equipment, so she doesn't need 30 attribute stones. Unless assassins have attribute attack weapons, their skills are attribute-free. As far as I know, assassins with weapons over 60 seem to have no attribute attack, and assassins take strength or independence. It's up to you to buy the equipment or not. Wu Ji is definitely easier than an assassin in drawing. I mean hand speed, assassin hand speed.
