Changes that will make Zyra great again
Give the range on her passive a big decrease, so seeds spawn only in a medium sized radius around her. As big as Jannas R sounds logical to me.
This will eliminiate useless seed spawns and give her passive a new purpose. This is how i see it, the seeds on her passive should be used defensively while the seeds from her W should be used offensively. Zyra is extremely squishy and she has no escapes, she has to put up a fight on the spot to be able to get away.
https://boards.na.leagueoflegends.com/en/c/developer-corner/xVQr7ihf-mid-year-mage-updates-zyra-direction Players who attack an entrenched Zyra should be very afraid. < Riot said that this was the direction they wanted to go with Zyra.
If this change happens Zyra will always have seeds scattered around her, making her less vulnerable to ganks and boosts her survivability overall as she will always be able to put up a fight and the direction Riot wanted to take with Zyra will become reality, which right now isn't.
Increase the range on her Q, she needs this buff due to how hard this ability is to hit and how squishy she is to make her safer.
Decrease the cooldown on her W and make it so that this ability doesn't get affected by CDR. Zyra can only store 1 seed every 20 seconds early game which is INSANE and this also forces her to rely on the random seed generator that is her passive. 11/10/9/8/7 sounds good to me.
