There is. Axes have a ghost skill already solely for axes with it's own special effect/hit buff which even ties into another ghost axe skill... why do they need further augmentation when they aren't the ones lacking. There's also plenty of ways to work around it such as sword/axe or polearm/axe weapons. And uhhh just because they aren't a class weapon doesn't mean duelist doesn't heavily imply that you can use polearms. (Vent Petale, Sillcut, Couloir, Cyclone Spear, Lance de Lion, even Repel)

So shall we start adding polearm and axe skills on to kensei next, by that logic?

You're just running in circles now. People already use polearms with kensei theres just no skills for it. Your axe wish has already been granted by ghost nor is this an axe topic please don't contribute if it's not about the post. If you'd like an axe skill suggest one.
