1) The percent dmg was burst rather than dot so there is less counter play.

2) The damage of Kha missing health ability is much higher than Fizz's. The ability being good base value + amazing scaling + percent health damage.

3) The ability had a low cooldown this allowed a very high base damage ability to be used which had a lot of inflated power. Both isolated and non isolated versions of Q was way too strong.

The ability had so much power it is clear to me that they decided to strip it of unneccesary power. If you look closely at the patch history the isolate evolved version now deals the same damage as the pre nerf isolated taste their fear.

They removed a large amount of power and the %health was just free power that scaled very well at all points of the game and could be applied more than once with the ult. It was just too strong to balance on a low cool down spell so they made it more linear and controllable with a level scaling fixed damage.

I'm not a Kha expert this is just my interpretation of the nerf.

tldr too much damage in a single ability riot toned it down.
