User blog comment:Ozuar/Kha'Zix - My Conundrum/@comment-1488423-20130410161454

What I've done on Kha'Zix is this:

Max and evolve Spikes first for ranged harass, sustain and slow after leaping in

Maxing claws second but evolving it last.

Maxing leap last but evolving it second. Gap closers/aoe's are too important when jungling and useful when laning an assassin.

Evolving your ulti is never really worth it except in a few situational cases.
