I was only correcting the fact you said "All he can do is walk around it and by that time its probably gone anyway", I wasn't denying its strength as a skill.

However, that being said, it has limited application. Most long ranged champions don't use projectiles (such as Xerath, Lux, Kog'Maw, etc), and those that do (such as Nidalee and Ezreal) will only lose 1-2 abilities. It's strongest application is disrupting AD carries - but very few fights are so immobile that an ADC will "miss" more than 1/2 attacks.
