Would it be possible for us to, later down the road, see an ax tree pop up in Duelist?

Ghost builds off of the concept of using Axes, but axes as a whole just really aren't supported in the slightest by Duelist. You get +CRIT, fleur, etc etc, but that's about it. Those benefits, alone, can't even be attributed to sword/spear/axe, due to the fact that anyone who is a duelist can get such a boon (though that is probably a balance fu thread waiting to happen).

I really have no idea what the skills would entail, but just some more support going to Ghost (and a berserker class in the future maybe) would be lovely to stack up with the berserker shell, etc.
