I'd require any reach weapon to be 2H
thats why I'm not a designer....
Actually Versatile is the weakest attribute by far IMO. It only gives a non-scaling +1 damage if you use the weapon in two hands. The ability to use a weapon in one hand isn't an attribute and to use the +1 damage you have to give up that shield. The only time I see it as a real bonus is if your class can't use a shield. The ability to hit someone an extra square away seems a lot better than a possible extra +1 damage [if you're using a shield, the attribute does nothing for you].Versatile is strong because it include the fact you can have a shield (So +2 AC and Refl).
