Jinx effect has to be nerfed and Rose balance ideas

Hi! Here's my humble opinion on Nec'Rose's jinx ability.

It's a very powerful feature but I think it can be more balanced, here is where the problem is: 

It causes you to take 40% more damage, which is insane since characters like cacti, peashooters have such a powerful shot. Also, it lasts for 7 seconds (I don't know if this is true because I couldn't find any information about the duration of the Jinx effect so I just assumed that), however it can be purged by any type of healing. 

Here are my possible solutions:

1) Reduce the amount of bonus damage of Jinx but increase the damage of Staff of Jinxing. That way only Jinx will be nerfed but Nec'Rose will keep her damage.

2) Decrease its duration by half (or more) and not let it be purged by healing. This will make Rose and her teammates to be quicker in order to engage jinxed Zombies but giving Plants a gap to secure a kill or just do significant damage.

3) This is not a Nec'Rose only solution but the whole class: reduce Rose, Druid Rose damage by 1 and decrease Jinx bonus damage but Increase Time Snare duration to 2s and increase Goatify projectile speed.

Overall I don't think Rose is in a good, balanced spot right now. The way I see her it's a hybrid support/dps class and not to much on the supportive way.

Okay, that's it! Thank you for reading.
Friendly reminder: I'm a Rose player, I have over 800hrs on Rose. Not trying to sound entitled but I think a have the experience to know how to balance her.
