Can Evelynn get a new passive? (Or something...) [Rework ideas]

I hate her passive. Its stupid, and has few good qualities. Being invisible isn't good unless you can sneak up on a enemy. Evelynn can't do that. Can we just get rid of it?

I've some ideas on what I would do to her kit if I could add some ideas.

First, I'd change her passive to have a ability effect with her kit. Her passive will leave a mark on the enemy (not dealing any bonus damage or added effects). This mark can be activated by her Q, E, and R. Her secondary passive will have her gain bonus MS based on 5/6/7% of her AP.

Evelynn's Q will instead of dealing random spikes to enemies, it will send out spikes to a specific target dealing the same damage it already does at the same cost. Each time Evelynn is able to deal damage to the enemy with her Q, the passive refreshes. The Q will now have a 50 increase in range.

Her W will be the same as it is, but have a reduction to its cost as its leveled up; 40/30/20/10/0 mana.

Evelynn's E will be changed a little, where she will deal what it usually deals, but it will instead automatically give her the AS, and her first basic attack (to non-structures) will be dealt the massive damage (not bonus damage).

Evelynn's R will be (sort of) drastically changed to instead of dealing damage, it will still be a initiating ult that snares enemies and reduces their armor and magic resist by 15/20/25% (+1% AP) for 1.5/2/2.5 seconds. It only snares in the usual field it would damage. Those with her passive on them will give Evelynn a 25/50/75% increase in damage to said champion(s) snared.
