So this is a new weapon concept. The point of these weapons isn't really so much to deal damage to opponents, but it has stupendous knockback, every gun shot, or bomb blast, or sword swipe has its own knockback, with some damage, and then is followed by a strong gust of wind from the weapon that pushes the target even further back. In addition, to the knockback, to compensate for the lower that average damage output, gust weapons have a chance to stun the target.
