If the Garlean sheath is actually a hint towards the Samurai class, it's possible they might wield elemental blades. In FFXI they had 3 elemental Tachi, Goten, Kagero and Jinpu or Lightning, Fire, Wind. The way his sheath potentially works is that it's infused with those elements, or maybe one of the other 3 not mentioned and it temporarily imbues his blade for certain actions.


When you think Samurai one of the traditional styles which appears to be called https://en.wikipedia.org/wiki/Iaido . Gave me the idea that perhaps what a Samurai could do as a DPS is draw from one of the 3 elements which would open up unique effects with certain combos, but the longer they stay in their elemental stance for the weaker their overall capabilities will be and they would need to sheath to recharge their elemental blade.

So imagine having something like Iaido:Goten imbues blade with lightning attributes raising crit hit rate but reduces effect with each weaponskill used. So maybe at 30 you start with 5 charges and by 50 you gain 8 charges, but you obtain abilities that allow you to imbue more mana into your blade to add charges but the cost would be more than starting fresh however it doesn't break combo.

So if you close your eyes and think about it Samurai would be about picking a Iaido to start off with then following through the combo until the effect wears off or you swap into a different Iaido and with "Meditate" ability, it could restore both MP and TP to self. At 50+ new combos could be introduced that requires you to change your element mid-combo but the give and take of switching your elemental blade is the mana cost behind it, similar to how Dark Arts can get costly if you keep using it. Some combos that come to mind in that respect would be Brushfire fire that follows up with Wind to create an AOE DoT, Thunderstorm wind that follows up with lightning to deal heavy AOE dmg, and Burnout, lightning that follows up with fire to deal heavy single target damage, the idea being that the lightning would burn the target from the inside and then the flames would burn the target on the outside.

We'll know what the two jobs are in due time though, but speculation is fun here and there, I'm just personally hoping that the playlist/animation for Samurai plays off with the fluid motion of the blade that you then reset when you change stance.
