Why So Many Slow Mechanics

Keep in mind this is from my current playtime. Every boss just has some kind of mechanic that slows or staggers you, which is not hard to play around so much as it is annoying mechanic that disrupts the flow of combat.

It feels boring especially with casters. You shoot on projectile then you dodge, you shoot a projectile and you dodge. Perhaps consider changing this to make the beginning part [where I am so far] a lot faster, and reduce the artificial slow downs.
