The top classes i'm having problems to hit as Assassin, in order of dodge:
That being said, a full VIT ranger won't save your life in any case, unless your focused on PvE aspect, while you get 2 points dodge per AGI on stats.
Keep in mind that Dodge is the second best stat after Vigor,(Penetration is better) if you manage to achieve an insane amount of Dodge, you'll be almost unkillable. (+ 10% Agi buff)
If you don't believe in the words im saying, try it yourself and experience the TRIAL & ERROR method, that's the best way to solve your dilemmas on stats on any game.
