AP Ezreal has no CC because if he did he'd be broken beyond belief. His DPS is not only high but unbelievably safe. Once he gets Goddess Tear and Rylais you'll never get close enough to hit him while he's always able to hit you.
If you've ever been at a turret that's being shoved down by a team with AP Ezreal you know the pain. Ult comes out and 1-2 people are down to half health. Qs and Ws are flying around like crazy because blue buff lowers the CD to nothing.
I personally think he's the highest skilled champion in the game because his DPS is so dependent on landing skillshots and unlike Cassie he doesn't have a targeted followup or a mana passive or an ult that guarantees positioning.
