I know Kha'zix is hard to balance, but are you even actually trying?

So I would like to address the balance of Kha'zix, in comparison to that of other AD assassins. First, I'm going to look at the problems that Kha'zix faces.

**THE EVOLUTION SYSTEM: ** Not all evolutions are created equal. And by that I mean none of them are good enough.

Evolved Q does crazy damage, but it has 2 problems. 1, the isolation distance is too high. 2, isolation is calculated not on cast, but on the landing of the ability. That gives the opponent just enough time to walk or flash into their teammate, and all of a sudden the ability that would have done 900 damage does only 300 damage. So the difference is almost 600 damage solely based on when the calculation happens. Oh, and because you did 600 less damage than you thought, you're now a sitting duck in the middle of their team with no potential for a reset.

Evolved W isn't worth it. You do basically no damage if you evolve this. Kha'zix Q does negligible damage (read: 104% bonus AD and 10 x level less damage than evolving Q, but only adding AoE and 50% slow). The sustain is ok early because you'll max this first, but it just sucks in terms of snowballing, which is what you have to do. It also delays your evolved Q damage until level 16, which is not helpful.

Evolved E is great, but it has no benefits of getting it first. Resets are great, but if you have no damage to actually get kills/assists, it doesn't help you at all.

Evolved R. Why would I ever get this ability? Ok, so being invisible for longer is great, but if you play it right, you would never need this. The only time I ever get this is if I win the event against Rengar and have the random convenience of being able to get a 4th evolution.

OTHER AD ASSASSIN KITS

What do other AD assassins that remain semi-viable have that Kha'zix does not? Kha'zix has one of the highest single-damage abilities (on a 3.5 second cd) in the game other than possibly an infinitely scaling Veigar or Nasus Q or Veigar ult or maybe a full range 1000 AP Nidalee spear. So how then do the other AD assassins stay ahead of him?

Well, one of the things every other AD assassin has is damage amplification or an AD steroid. Zed has scaling bonus AD based on his current bonus AD. Talon does an extra ----% damage after using his E. Rengar's empowered Q gives him an extra 10% AD, allowing him to beat most champions in a trade. Master Yi gains 10% AD with his E passive.

Another thing that every other AD assassin has is Attack speed scaling of some sort. With Zed, while not scaling directly with basic attacks, his synergy with and gives him a lot of AS and lifesteal that he directly benefits from. Talon is very similar. The problem with building Kha'zix this way is that he then lacks the straight up attack damage that he needs for his ability scalings. If he was to build BoRK and Ghostblade, he would be missing out on a lot of AD that his Q needs to be able to kill someone. Talon deals more autoattack damage with his passive, and thus gains something from being able to autoattack more often. Rengar has a huge AS buff, as does Master Yi. Kha'zix gains NOTHING from building these kinds of items.

The other notable point is that Rengar, Zed, and Talon all have incredible 100-0 potential. If they use their entire kit immediately without anyone interfering, they will likely kill the target with no issue. That whole process takes about 2 seconds. Kha'zix, however, lacks the kit to be able to do that. He must be played more like a sustained damage dealer, which makes no sense as a bursty caster. While you may deal a ton of damage with evolved Q in isolation, in the couple of seconds it takes for the ability to be back up, the champion you targeted is likely no longer in isolation unless they really screwed up their positioning.

SOLUTION?

How, then, do we give Kha'zix some sort of balance compared to these superior assassins?

For one, he needs counter-counterplay. The counterplay to isolation damage is to not be isolated. The issue then becomes that they can stand near their teammates the whole game long and not be bothered by Kha'zix leaping in and dealing negligible damage. So isolation cannot be the only mechanic at work.

Here's my proposal (not necessarily all of these, but mix and match for balance).

Passive--unchanged Q--Increase base damage and reduce scaling by a bit, reduce isolation range by 100. Evolved Q--Increase base damage. (allows for the evolution to give a benefit outside of isolation) W--Kha'zix does 2/4/6/8/10% increased damage to enemy champions hit by void spikes (no extra damage for evolving) E--Applies a slow of 20%, increased to 30% on evolution. R--Passively increases AD by 5/7.5/10% upon evolution/rank.

Let me know what you think.
