Zyra ideas
So Zyra needs some changes. Mainly her passive but also her play a bit.
So just thought of this idea
Giving her W a bit more to it Zyra's seeds rejuvenate any ally champ standing within 120 units from a seed when a enemy minion/Champion/Monster dies within 300 unites of the seed Heal 2/4/6/8 HP and 2/6/10/14 mana per W level. (kind of like the support laning item that gives gold and HPs does)
That way as mid lane you could use one of your seeds to sustain (giving up some threat because you have one less seeds to use to fight) and gives her a way to help her ADC as support. Even help her jungler by dropping a seed near a camp for them.
It would also make it more reasons to want to squish her seeds but also be risky because she could Q,E them when you try.
Then her Passive Make it so When Zyra is in the Wild (any place on the map that is not a lane) or in bushes she is in her element. Zyra gains 2 armor and 2 Magic resist per lvl, +10% movement speed and her plants poison her targets for 4% of the targets max HPs over 3s (does not stack)
This way she wants to fight out of lane or from bushes and also helps her when she is alone in the jungle.
