Thats a little unfair. You try R1 spamming vs Darkeater Midir on NG 7+ and you're gonna have a bad time.
I agree DS is more reactive but you literally need to start moving when you see the body movement starting, and we're talking a matter of milliseconds reaction time really or its too late and you get one shot. So you need to have a good understanding of the move set of the boss as well as godly reaction times and you need to dance and bait out attacks to get an opportunity to attack yourself.
nergigante you can literally dance around his face and juke his frontal attacks to keep him in place and hammer away at the head.
