Ezreal [W Thoughts, minor change]

Pretty simple ideas here. Ezreal lacks one thing that every other good ADC has: waveclear. His ult can't even clear a wave effectively.

So, to put this simply, change his W to do damage to minions.

There are also a few other things you can change/take a look at, none of them being that important, just some things to be thought of.

1. Reduce base damage by X, give it a small (.3 sound familiar?) AD ratio.
2. Make it decrease damage for every enemy it passes through, to a minimum of X.
3. Cap the damage it does to minions at X%.
4. Decrease/adjust mana cost, decrease/adjust damage

All of these thoughts are to give his W more use whilst keeping it from bringing any unnecessary power. Also trying to affect AP Ez as little as possible, although this would be an extreme buff to him. (That's why I suggested the % damage to minions, so it doesn't make AP Ez too strong at clear waves and then roaming/harassing or something.)
