Kha'Zix changes and buffs

Wrote this on the LoL subreddit (here is the link http://www.reddit.com/r/leagueoflegends/comments/373duc/khazix_changes_and_buffs/) after seeing a Kha post here on the front page. I decided to also post it here so hopefully more people will read it. So here it is.

Kha'Zix is currently extremely unreliable, making him a not so good pick. There are many changes I would like to suggest so it's gonna be a long read.

Potential change number 1: Giving his isolation the Garen treatment, at level 7/12/17 his isolation range becomes lower, and at level 12 minions no longer prevent isolation. This ups his reliability by a large margin and gives him more oppertunities to 1v1 in minion waves.

Potential change number 2: If Kha'Zix hits the target with his W he marks them, if he casts Q on a marked target it consumes the mark and Q deals damage equal to isolated damage. I'm not really sure if this would be good balance wise, since most squishy people blow up if you manage to hit them with one isolated Q, and this change would most likely make him OP if not broken

Potential change number 3: FULL ON REWORK INCOMING, PREPARE. This is much more drastic but I decided to put it in here anyways. His passive now read: Each time you deal damage to a target you apply one Prey stack, stacking up to five times. Each ability gains different bonuses from Prey so I'll start of with Q

Q: Deal damage and apply 2 prey stacks to the enemy, for each prey stack you deal bonus damage based on missing health (damage is calculated before you apply the stacks)

Evolved Q: More bonus damage, the bonus damage is now TRUE damage (maybe too strong, not sure)

W: Same as it is now, also applies 1 Prey stack

Evolved W: Now reduces the its own CD if you hit a target with prey stacks, more reduction for more Prey stacks

E: Same as now, applies 1 Prey stack

Evolved E: Same as now, not adding any power because I feel it's good as it is

R: Same as it is now, plain and simple stealth (remember auto attacks also apply Prey)

Evolved R: Gain a third charge on your ult, and your auto's deal bonus magic damage after casting your utl

To clear up some of the wording etc. I'll show you how much Prey a standard combo give.

In this case you have evolved your W, Q and E

You E on the target, they now have 1 prey stack.

You auto them once, they now have 2 prey stacks.

You use your Q dealing bonus TRUE damage.

After dealing the Q damage your add 2 prey stacks, you now have 4 prey stacks.

You now cast W and reduce it's cooldown by X seconds and add 1 more prey stack.

You end with 5 prey stacks.

This is all I had to say, just wanted to share this with you guys.
