[Vincent] How good is he really?   [9]

After many many months I finally hit Guru 3.
Hardly spent any money and big thanks to all who have sent me your veteran tickets since they was first added!

I just finished getting him to max level from dispatch and now faced with hard choice. Do I replace someone to use him and 5* or do I just leave him be?

I know what his skills do but never used in PvE not PvP (Well I have but its was an old vets called X... something, Xaiya I think, who don't play anymore and this was ages ago..) How good is he really vs certain hunters? I remember the days when he was a natural 3* but now he is a 4* (and you get given him in T1..)
