I think you are just getting trolled.
Even though you could go with Hoplite as a Fencer, you can only use 2 skills with Rapier: Pierce and Stabbing. You don’t keep the Finestra buff when you swap weapons and all the other skills are unusable while using a Rapier.
Sure, Pierce and Stabbing and pierce-type skills which in theory should have good synergy with Fencer’s Attaque Coquille, but in practice that is not the case. Not only that, but getting 3 circles of Hoplite is a massive waste considering how little you get in return, and it also leaves you vulnerable for future PvP content (as you get close to no CC).
At the same time, Fencer skills cannot be used with Spear, so there is a massive conflict of synergy between the available skills that build has.
Swordsman C2 is also a waste in my opinion. You never really auto-attack as a Fencer, and you get a lot more benefits from Peltasta such as:
- +18% evasion when using Guardian (Fencer’s love evasion)
- Manual block with C (+25% block and +25% defense while using it)
- Swash Buckling (AoE taunt and +25% HP when using it)
- Chance of 3 second stun when using Umbo Blow (for PvP while using a shield, if you are interested in that)
You lose a lot from not going Peltasta, especially as a Fencer.
Which leaves you with two main options: Highlander and Barbarian (Rodelero maybe if you want to sacrifice PvE for more PvP, but there is no real PvP in the game yet).
Highlander gives you Bleed on C2 and Armor Break on C3, while Barbarian gives you high-damage AoE skills that can stun for 2 seconds.
While Highlander currently has a 0 CD Sky Liner, that is not much of a big factor in a Fencer build compared to other builds, as you get Flanconnade.
So yeah, go Highlander if you want debuffs or go Barbarian if you want stuns, and take Peltasta.
I don’t think that whoever made that Hoplite C3->Fencer C2 build has any experience playing Fencer, or even played the game that much considering that the only reason for choosing that build is reading the description of the skills with no knowledge of how it could actually play in the game.
