It’s just to serve a point that the alternatives there are for this game are much worse, and that you don’t have a clue about what you’re saying.
On top of that, you still haven’t given a single example of what difficulty you’d like to see instead of interrupts.
Really sounds like a poorly camouflaged request for big nerfs.
Also:
Aren’t you doing like 15s? There are a lot of casts you can ignore/miss in those key levels.
