"You can still play optimally with 1 button rotation" no you can't, every 5 abilities you lose a second of gcd. You're hitting 6 buttons in the time someone actually playing the game is doing 7, and on a mobile where the player is hitting 70 things, you're only doing 60, or yk 15% less damage than them. And that's assuming the one button rotation is customizable/actually optimal, and reactive to things like hot streak on fire mage or rsk resets on monk. If it's not, you're losing even more. Could be the difference between enrage timer and not. This just adds one more thing we have to avoid in high keys/heroic raids, gg I guess
