I get what you say, but riot tried to make them "less snowbally","make counterplay possible".
I dont think rengar fits any of them, rather the oppsite.
Switching from a Empored AA to an Abitlity with 2 phases might indeed feel a bit more clunky, but have you seen the scalings?! + have you seen his possible AD values!? that is just nuts! you dont even need the empored Q, a Ult Crit+ Q is enough to make squishys less then half life, while the empowered Q just delets them... and those are technicly AA resets too.
Just so you know, i think that his empowered W is broken/unheatly as hell. and should be removed ASAP.
you can cleanse WW Ult, MalzUlt etc. and all on a basic ability for free, for 1,5 SECONDS!!!!!!
Oh and did i mentioned Edge of Night? with ANOTHER spellshield?!
I dont care what rank you or me or others are, i only value facts. And the fact that if he gets fed he becomes unstoppable, un counterable after he gets ~3 of his stacks is not so good.
And even rengar mains are still in the learing phase so im rather trusting in my numbers then personal opinions
