LOL If all the best weapons were pink, would that make pink a good attribute? IMO the designers use Versatile as a penalty, not as a bonus. It's there to stop halfings from using bastard swords and not as a real bonus to the bastard sword wielder.I think it's more in the mentality of the designers. At some point, a weapon become so big that it can either be a 2-handed weapon, or you can give it Versatile. I don't think you'll ever see a weapon +2/1d12 or +3/1d10 that is neither versatile or 2-handed.
But I agree for most military weapon (like Longsword) Versatile is pretty weak, even annoying for Small character.

So did this proposal pass? If so, what are the exact stats of the Great Halberd?
It passed: Great Halberd / +2 proficiency bonus / 1d12 damage / axe, polearm / reach, high crit/ 30 GP / 16 lbs.
