Yeah, compared to the variety of polearm and even 1hand weapons, two-hand is definitely lacking. 3 non-ct blunt options, 1 pierce, and a ton of long high cut damage swords. There's a lot more that could be done for variety.
With the variables of speed, weight, length, and damage/damage type, there are an infinite number of things which could be done to make each weapon more unique. Like, why is there not a super long, super fast, medium weight extremely low damage two-hand? Things like that.
