@Yashiry Try this one out bud 
Sorry for the late(ish) reply 
This is the build im using (or will finish using).
Rank 1 - 3
The reason to have 1 Point in Thrust is simply for the Bleed Attribute, so be sure to get it.
You combo it with either Restrain or Helm Chopper.
Rank 4
The reason for the Barbarian is in Cleave, giving you an extra 50 Crit Rate to your build.
Helm Chopper is also nice to combo with Thrust for the Bleed and for the extra Stun.
OR
If you dont plan on going with a Crit Build, then opt for Cataphract or Hoplite, giving you more damaging tools and access to Spears.
Rank 5 - 7
After that you have Corsair, which i explain in the video you watched 
Rank 8
Lastly you have Shinobi.
Shinobi is the icing on the cake, bringing you awesome tools like the Clones, further increasing your damage!
Hope that cleared things for you
