We don't have any real use for Blaster weapon granted it is the default, and its not much different than Split shot.
I think the blaster weapon should be the most sensitive to "projectile size modifications"
At least with low damage an Oval Ring shape or bubble would cover more ground.
I think Weapon size should be a lot bigger with this weapon
Think of it like this: slow, floaty, & wide.
At least this would make the weapon build useful and more fun, and everyone loves bubbles of death.
You could make this another weapon altogether but Blaster really needs some practicality, otherwise you may as well let us choose a weapon with some re-rolls at the start.
