I just came in here to laugh at all the people going "You can beat it by memorizing each and every ability the boss is going to do, rather than reacting to what's happening on-screen like a normal human."

Certainly when you learn a fight, memorizing things is important, but when you have to go purely by memory because the tells are so delayed by the server infrastructure, you've got some massive issues. And going "These issues don't affect me," is not only akin to saying "It must be something on your end, I've smoked for 25 years and my lungs are fine." but it's a complete and total lie.
