Yeah, I noticed this as well. Especially noticeable for me considering I have 280 ping on average and the first time I fought Acheron, I thought I'm in hell until I started trying to dodge his attacks. Not only I ended up dodging everything on reaction, I had FUN, unlike a certain primal fight I know. Then I started paying attention to the other fights, especially King Behemoth's Meteor. I've seen plenty of last second dodges on meteor that looked perfect in motion.

I like this and would like to see more of this in future fights, including the ones that have tighter window.
