I realized that it's hard to make a 5* for this weapon that's not OP. So instead of doing a major damage buff for the 5*, give it a status buff. Make it so the 5* has a chance for stun. That way it balances out it's lack of DPS, as for the dodging enemies "problem" either give the projectiles a larger range or make them explode.
I also think the charge and functionality of the line needs work. Shield canceling is very difficult with Winmillion; not to mention how the charge attacks projectile can be canceled!
As for a name and look for the 5* I am unsure. Maybe something like Turbulent or driftant.

2 you inflict stun you have to hit at least once. with things not stunned, it's practically impossible.
