Not really, as it's at -2 AB
But I currently have two characters that finished Chapter 1, can't really decide on which I shall focus and (maybe) finish the game.
1. Strenght based tripping Oni-Spawn Tiefling Vivisectionist (with monk dip for AC and sword-saint dip for fauchard prof. and focus) and
2. Dex based human scimitar Sword Saint (with monk dip for AC)
Both will have shatter defenses for easier hitting of enemies (in case of Vivi also for easy sneaks - even when not flanking). Neither will take Power Attack/Piranha Strike.
Vivisectionist will have worse accuracy but much higher damage per hit. And will eventually greater trip almost anyone, disabling primary threats and causing lots of AoOs. Low HPs with moderate AC are a problem, but perhaps weak-ish Will save even moreso.
Sword Saint will have great AC (and defensive buffs!) and accuracy plus burst damage capability when needed. Better party synergy too, as he can main-tank, so much more freedom in companion choices. Therefore I am leaning towards the latter.
