How to make EZREAL fun and competitive !?!?!?!

I have been playing ezreal alot recently. He is a fun champion to play but he lacks quite abit in some areas such as waveclear and damage to tanks. As I really enjoyed playing ezreal I have a couple of suggestions on how ezreal could be improve and I would love to hear some opinions on it.

• Ezreals Q Mystic Shot: I think that in order to make ezreal a viable option and his Q should have a little area of effect, that is just big enough to catch all three caster minions if the Q is shot at the middle one. The area of effect would not have much of an impact in teamfight unless the enemys were standing on top of one another. This change would greatly increase his wave clear.

• Ezreals W Essence Flux: I think that in the state it is currently in is useless as it is like a tickle to the enemy if they have a half desent health pool. I think the change to it should include the addition of percentage max enemy health damage starting at 2/2.5 and scaling up to 10/15. ( The values could be changed or even only proc if the Q is the thing that procs it, making the ezreal player think on how to position or even if to use E to get in a position that allows him to get a Q hit without aa with the E. I think that this would define a good ezreal player.)

I think the skill order might change depending on game and enemy comp. The ezreal would have to choose if he wants lower cooldown on his escape or is it better to go with percent damage.

A third change I could think of would be to allow the ult to do enough damage to kill caster minions in one shot more reliable this might make the ezreal too strong so it might me a bit of a stretch.

I would love to hear thoughts and opinions on this as I think that ezreal is a really fun champion and should get some love.
