The players I have the most respect for?

[Anira-chu]

while you've clearly proven this to be true in your case, it still seems like insanity for some reason. My eyes go down to my hotbar just to check cooldowns but thinking about looking at my hotbar just to move my mouse to the correct one is unthinkable, i have no idea how you do it.

Easy: Muscle Memory.
The moment you have your skills position in, you don't really need to look at them. I also don't have tunnel-vision.
I play all sorts of classes (I call myself rather a main-healer but have fun with dps'ing and tanking aswell). My HUD is a bit more clutted on the left side, so I don't look across the screen on partylist, enmity list etc.
I seriously don't get why it's so unthinkable a person can be a pure-clicker without issues? Back then when I was still on PS3 and had to switch bars, that's when I started to had issues. Switched on PC, being just a clicker since then, no problems.
It kinda depends on the person itself, honestly.

if I could make an ex-run of whatever primal with an eye-tracker, people would see how I would look at the screen.. but I don't have a VR

(edit: ugh, forgive me any typos or whatever I no found yet. I rather should be in bed now)
