99% of Kha'zix damage isn't just in Q, but in Evolved Q, and only on isolated targets
I can not see how that is in anyway the most stupid design decision I have ever.
I also can not see how making his Q a must evolve or he does 0 damage contradictory to Riot's goal of giving Kha'zix players more options in evolution path in anyway.
I can not see how often someone will let themselves get isolated when a Kha'zix is around.
I also can not see the unparalleled awesomeness on using an evolution point on his W over his E or Q.
And what I definitely can not see is how Riot decided to make Kha'zix 100% isolation dependent when they initially buffed his Q in the first place SPECIFICALLY because nobody was STUPID enough to evolve his Q BECAUSE it only worked on isolated targets...and that was back when his isolation mechanic wasn't absolutely nerfed to oblivion...and back when his W was actually viable.
Then again I also can not see why kids love Cinnamon Toast Crunch, so what do I know?
