Jinx and Attack Speed vs Varus and Passive

Anyone else think her attack speed is a little faster than others? Like, I know that her AS bonus for each level-up is lower than all others, but her Q' passive makes up for it by stacking up to 30/55/80/105/130% bonus AS.

So Jinx has 0.625 at level 1. With this passive, after 3 stacks, she will have 0.813 AS at level 1.

But what about at level 18? And without items, and by now, Q is all leveled-up. So, she has 0.738. And with her passive, she is granted 1.7 AS right there with no added items.

Varus, who should be all about AS, cannot be able to use his passive in a team fight like Jinx can. He must instead rely on his other abilities. But what of the passive? Well, to be honest, its actually not useful. We've gotten to a time where kills are harder to get, and Varus won't be able to just come in and kill everything. The AS for his passive should be a permanent stack of up to 40% bonus. With each minion kill, he receives +1%, with larger minions he gains +1.5%, with monsters he will gain +4%, with assists Varus gains +5%, and with kills Varus receives +10%. When dead, he loses either all or half of his stacks.
