Uhhh...with mana regen runes and masteries and Goddess Tear you should be spamming Q whenever possible. Makes farming easier. Ezreal can't shove so he's susceptible to mids like Morgana/Cassie/Ahri/Gragas who can shove mid and then roam.
His Laning Phase is AWFUL but good lord after that. The only AP mid I can think of with a stupider Poke Game is Kog maw. But Kog Maw is much less safe.
