Well, as a main rapier player I actually should have made this topic, but did not because I have yet to make a good build out of Matador (I was focused on polishing the Fencer3Shinobi during this time).
The thing I will say is, Matador is not optimal yet for PVE, even with the buffs to come, and I say this because he is too much of a tanker, he kinda focuses a lot on the early dodge tank aspect that Fencer had.
Now, it is not that Matador is bad on PVE, but most people here want to make the highest and efficient damage possible on what the class specializes for. And Matador actually loses in that area to a lot of old builds.
Note: I was making some calculations, and Fencer2Matador2 actually wins out Fencer3Matador1. But if you consider Epee Garde, then it loses. Also, both loses to Fencer3Shinobi, mind you.
However, there are two places where Matador might be necessary, even. This is just speculation, though
1-New DG 330 - Pretty much all mobs there are Beast type. And Matador is a Beast type killer with Muleta. I believe he will be a core DPS against that damn Kugueri boss.
2-TBL - Now, one thing that IMC did for rank 9 was making good TBL tools. And with new Paso Doble iframes, we finally have something that could counter even hook from corsair (still pending confirmation). I would not say that Rapiers will be first place on TBL, but we do have a better spot on the PvP scenario now compared to what we had before, where only shield builds were the norm.
I will do a Matador2 build later, but not now. It will be for sure Peltasta with Fencer2 (yeah the old path). I believe that the strong point of this class is the DEX stat, frankly, so I will focus on doing that.
I’m currently building a Matador2 for TBL, but it might take some time.
