It is counter-intuitive because your ability is meant to by reducible by attack speed, via contradictory indications on your ability and its additional info (1 / attack speed is incorrect past 1.43 attack speed), and is there simply to make the ability clunkier, as it would otherwise be another order of magnitude too strong, without really fostering interactive gameplay. By contrast, and  have a delay to allow their opponents to dodge the ability. A delay on your Q doesn't make it that much more interactive, again due to its spammability.

Using for comparison also doesn't work that well, since  can only use it to block attacks and projectiles for a limited duration, whereas Eurya can permanently nullify all projectiles if he has more attack speed than his opponent.

I would also advise you to analyze your own champions qualitatively, and not just quantitatively. Numbers are usually not the biggest issue on a custom champion unless they're clearly bonkers, but the gameplay presented by a champion's kit matters: is this kit healthy? Is it interesting? What does it achieve? What does it bring that's new to the table? The issue here isn't just that several mechanics on your Q are broken (along with a few others, such as Eurya's W passive), it's that your kit lacks clarity and synergy, and has a lot of mechanics that are objectively not fun (cleansing an enemy of buffs, for example, or permanently hard-countering ranged enemies). I'm giving feedback to help you figure out how to improve your champion, and rejecting it out of hand simply because it isn't worded as a mathematical proof is neither a mature nor a productive way to handle criticism.
