Ezreal, balanced? you decide.

Ezreal as you probably know, is one of the highest tier marksmen right now. I bet you're wondering why (if for some reason you don't know.) Let's a moment and evaluate his kit shall we? Ezreal has 3 skill-shots, and a built in mach-flash. Both skill shots scale well with AP, (considering the base damage, and CD) and mystic shot scales with both ad and AP. Now, that sounds balanced, and for how squishy he is, I would tend to agree. However, one thing he has, I just can't accept. Mystic shot applies on hit effects. Why? Well we don't know. Ezreal has one of the few skill shots that applies on-hit effects. If we compared that concept to say..... urgot. Well that would be over powered as hell. Imagine if acid hunter applied on hit? Well that would be crazy, urgot dps would shoot through the roof, and no one could beat him. (cough cough) I think Ezreal needs to have this feature re-evaluated. It doesn't make sense, he already has a very long ranged, and safe kit. It's like if undertow set off shiv, or piercing light, or boomerang blade. I'm trying not to rage, but I seriously think this needs to be looked at. Due to recent updates, I think this needs to be changed to promote a healthy all around Ezreal.
