The counter-intuitive delay does not prevent Eurya from having on-demand and low-cooldown access to projectile destruction. Even if he were to block, say, 30% of the enemy's shots, that would still be too much, and the spamminess of the ability means the delay doesn't really factor that much into significant counterplay. The problem isn't just that this ability is objectively too strong, it's also that it's just not that good for gameplay. There are better gameplay hooks to give your champion out there.
