Just playing with ideas and unwanted (but thematic!) buffs to Zyra as usually
Why does the fact that she's a carnivorous plant reflect nowhere in her gameplay?
Hear me out first and downvote me later, but please keep in mind I'm only playing with ideas here:
Zyra has 11th lowest base health on level 1 (counting unmounted Kled, otherwise she's 10th) in the game and 7th at level 18 (counting unmounted Kled again). Given she has no inbuilt survivability in her kit, what if she consumed enemies? In other words, what if she healed when plants damage her enemies?
It would reward those players that can kite around her plants and actually helped her in extended fights, since introduction of 
trashed this ability of hers and her burst is so so anyway, given current meta of shielding and healing supports. (This is my opinion, you are allowed to disagree.)
Now I don't think about anything big, for comparison: 
heals when damaging poisoned targets with Twin Fangs (E) by 5-22 (based on level) HPs. That's not so big, is it? Could be even lowered for every other plant attacking (the same as it works for the plant damage - every other plant after the first one deals 50% damage).
I know noone enjoys playing against her because she's a lanebully, but with this change if you poke her or a jungler ganks, she'd actually waste the seeds she stacked to heal from the minions and couldn't use it to poke you, think about that! Speaking mostly about the midlane where I play her, I cannot comment much on the impact on support role because I don't play her there, but theoretically I guess she'd push the wave for her ADC this way and need to recall anyway as good junglers are focusing botlane the most now and she'd open herself to ganks.
Now that her winrate was decreasing according to op.gg for a few patches (except the current one which still has pretty little data and keeps Zyra on 50% winrate as opposed to previous 48%) I guess a minor buff wouldn't hurt the game much, would it? Especially a selfish one.
Edit: If someone actually thinks this is bad, please, tell me why do you think so. I'm open to an objective conversation.
