I think ezreal is due for a rework...
Ezreal's kit is just designed to abuse things. He's abused things so much that they have been nerfed solely because hes used them. Right now, were seeing the kleptomancy rampage.
But unless ezreal gets a rework, this is just gonna keep happening.
Nerfing ezreal's Q wont change anything for the good, it's just going to hurt him and keep him from being useful at all.
Looking at his kit:
Good Q that applies on hits with high damage an low cooldown
Garbage W that serves to give tear charges
A blink
A lackluster ult that is only good because of the cooldown reduction from Q
A passive that gives attack speed on a champion thats spamming Q's instead of autoing most of the time (Yes in full fights you use autos) but all other times you're just throwing out poke spam..
I think this shows that ezreal's entire kit is just abuse. He only works if he has something to throw at the enemy and do a ridiculous amount of damage/scaling...
That doesnt sound like healthy kit design. The kit doesnt have anything to it other than Q and E, and its just boring to play as and against. Q spam.
Please, rework ezreal. Nerfing ezreal wont stop this abuse identity.
