I like cutter but for gimmicks only, I agree winmillion is better than cutter lines.
Also what if cutters have msi bonus.
I also have some hopes (0.01%) for a 5* elemental/shadow winmillion.
It would also be awesome if its charge attack would push targets along with the projectile and spawns a small vortex after the bullet dissipates :)
I agree that these are some of the weakest swords in the game. I'm not sure that Winmillion is better. I can't seem to get my Winmillion to do any damage.
The Cutter-line swords are kind of fun, though. The game is a better place for having them, weird as they are.
