Kha'Zix needs to have his kit better developed.
I love Kha's kit personally however I think there should just be a few tweaks to him.
Personally I believe they should focus even more on his Isolation concept. Putting it in his other abilities and making him more dangerous when he finds a prey alone.
Passive: much higher AP ratios Q: Higher NON BONUS AD ratios but removes the Isolation from unevolved Q Q Evolved: Stays the same but with even higher BONUS AD ratios
W: REMOVE DAMAGE, Increase healing AP ratios and base healing, take away the healing restriction and just make him heal on hit. W Evolved: Fires only one missile like the unevolved form but whoever is hit by the missile is slowed by 60% and everyone around that unit is pushed back so that the unit who is slowed by 60% is Isolated.
E: REMOVE DAMAGE instead it reduces all target's armor and magic resist by 5% Evolved E: Same Evolved E but if Kha jumps on an Isolated champion he reduces their armor and magic resist by 15%.
R: Same unevolved ult. Evolved R: Same evolved ult except he also gains % bonus armor and % bonus magic resist.
(The evolving is in no particular order) Assasin Kha - Would evolve Q, W, E Tank Kha - Would evolve R, W, E AP Kha - Would evolve R, W, E
The idea is to make each Kha different but providing something different with each evolve. For assassin(AD) Kha he would feel like live Kha but having to be more patient as the majority of his damage will be gated behind his Q. His E would increase his damage output on his Q and passive. Tank Kha would focus more on the utility that his kit provides. He would have an awesome initiation/pick potential but would not have the damage to follow up as his allies would need to provide it. His evolved R would provide more defenses so that he could survive fights much longer. AP Kha would be a niche pick. He would focus on staying in the shadows even more than AD Kha but would have crazy healing and passive damage. I believe AP ha would be a bit more hybrid based but I don't have the time for doing numbers for the sake of hybrid kha in a fan idea. Gosh guys you just ask so much of me you pricks. Love you all if you read all the way down here.
Please give me your thoughts and comments. Kha feels like an almost realized character.
