Depending on what you want to do:
A good all rounder is Doppel 3, taking highlander as base is more oriented to bossing whereas the barb variant is more aoe oriented.
=> Sw1/ Highlander 3/ Barbarian 1/ Doppel 3 vs Sw1/High 1/ Barb 3 / Doppel 3
For bossing Fencer is really nice with a lot of good synergies (barbarian fencer got 2 stacking slash debuffs, Attaque coquille that is the best “armor break”, the only one that is not 3 seconds long even if it is only for Piercing attacks)
SW (1-2) / Pelt (0-1) / Barb 3 / Fencer 3
Lancer is pretty decent in the dps chart (if you want to keep the 2H spear) but is a little be squishy (2 handed spear stance required) and will be a really decent pvp path. I’m sadly not knowledgeable enough in the lancer build but as far as I know Cataphract is really in a bad spot…
So to summarize:
- Fencer for heavy bossing
- Doppel for All-rounder (AOE + Really powerful bossing)
- Lancer for a more PVP oriented path but decent in PVE too
