Yeah, I figured one of the points of polearms is to use them for quick thrusting attacks, so it would work just as well for the two-blade style. Also, I made them a primal class (so they draw power from a dragon that Bahamut has linked them to). Originally this was going to result in super-cool magic attacks all over the place, but now it's just boiled down to they can do a range 10 breath attack as a basic ranged attack (Breath Blast). Now, the energy from the link just enhances their physical abilities and lets them jump all over the place... and breathe a quick blast of elemental energy.
