How about this. We’ll agree that animation canceling reduced your DPS to 10% of normal. Instead of 50dps you do 5dps with animation canceling. You want to do that?
If that’s not a good number we can adjust to whatever you like. Pick one. And we’ll continue. Hell use the videos you’re referencing to calculate the dmg you want if you want to be exact. But I’ll happily take an abstraction (this benefits you as you don’t need to provide extensive evidence).
