So glad it works for you. I see an AOE, and I'm out of it ON MY SCREEN, and still get hit. This happens dozens of times to more people than just me. And if you pre-emptively move, before you see the AOE, then you can get hit by a different attack or forget to hit your combo.

Dunno about the rest of you but I still look at my hotbar when fighting, I have not and probably will not memorize the buttons to where I don't have to. (Summoner was muscle memory but not new summoner and reaper is a definite no for muscle memory.)

Those people expecting this are elitests and way less than the number you gave.

Thats because you gotta move before the marker.

You get used to it.
