League of Legends (LoL) Question: Khazix evolution order

Hi, when I'm playing Kha Zix, I usually get W first, because of the slow and the area. Then, at level 11 (as I remember haha), normally get E or Q, depending on what their team are doing. Example: If they are spread out (alone), I get Q because of the damage dealt to lonely targets. If they are together all the time, and pressuring a lane or something, I get E, either because of the escape or the "starting team fights" potential. And, for last, I never get R, because I simply don't see me using that much. Well, that's it. Remembering that, if you pretend to jump into their teams, don't do it being full AD haha.

QER=ASSASIN 1 shot Kite until Next Reset DO THIS ONLY IF YOU GET AHEAD like 2 kils before lvl 6!!! OR IF YOU ARE SKILLED WITH KHA'Zix
WEQ=Pokerino VS enemy team with no hardcore enage and you want to poke them and engage or if you cant Assasinate bcs of champs like leona/alistar deniyng you hard
E=Never tried it seems worthless to me
Skill order QERevolves=MAx Q Then E Then W
WEQ=W E Q
MAxing E allows you to jump around every 7.2 secounds with 40% cds which is very vital on kha brutalizer and cd boots lizard elder and keep that blue sticked to you unless your mider is doing great.

what map ? top ? jungle ?

As far as I know from here say and what i've had most success with; W>E>Q or E>W>Q. Most claim R is a worthless evo, and W helps you clear faster, and makes it easier to hit people in general with W. E helps you snowball leads harder and Q was nerfed pretty badly a while back. This is all assuming your skill order is R>W>Q>E.

Hope this helps.
