Theory: Thief & Pirate heroes in December?

*Trying to picture a flintlock pistol with a grenade launcher attached to it*

Oh ye of little imagination! It's um... hidden Men In Black style...
Or they could just add it as another type of mech equip and screw the sairs / pirate legend.

Or the legend could be a SPACE PIRATE from the future (farther into the future than Bing ever was) with more modern guns that could equip such a thing. New category of Assault Rifle or something so that one weapon isn't stretched between 3 classes. They arrive through a rift opened in the space-time continuum caused by a careless / experimental Buccaneer's Time Leap.

They should just maket he brawler a 1 hand axe user so it's not a useless type of weapon.

Demon slayers?

The 2H Axe is much less common, only usable (effectively) by Heroes, and would smash through treasure chests / skulls in order to get more booty faster than a 1H version with a shield.
