Rengar is pretty bad at his role

First of all,hi friendly toxic rengar mains out there. I feel like we all know what he needs and what he doesnt. I believe he should be crit based assassin(like in old days) Make his Q be critical hit, makes his W a little bit weaker (in healing aspect) meanwhille giving it some sort of buff(like crits ignore 20%-30% of enemies' armor). And make his R crit again, while removing armor penetration. He should enter stealth a portion faster and would beice that attack speed increases speed of his leap(not how many tiems he can leap per secons, but his actual landing speed). And making it harder for him to land his E's(cuz they have delay on jump).

Would be nice if you leave ur opinions.

P.S. I have around 4k games with rengar and i've seen all shlhit he's been through and this would be nice change. In my opinion. If you're not rengar main, dont try arguing.
