The 2 problems you stated:

1. Has to make smart plays for escape/cc (how is this a problem? it's just a high-skillcap champ)

2. CDR doesn't work on her (it doesn't for any poison-based champ. And how do you think you fixed this)

Another one you implied:

3.People are spamming just to keep proccing the passive (In order to keep the passive up, you usually have to place your Q's incorrectly or end up wasting more mana. The question of whether you want to keep the passive stacks by spamming spells that you know will miss is an interesting strategic layer. Why would you remove it?)

And finally one you created:

4. Additional synergy with twitch, teemo, or even gangplank. Essentially, you're strongly encouraging that cass be used in a comp with those champs, and therefore discouraging her in other comps. There's not enough reason for this to make her less viable in other comps. The only thing like this is with Yasuo's  ult, but many champs have knockup, while only around 3 champs have poison.
