Goog one Riot, The only real buff to Zyra on the PBE didnt make it to live.
The only good thing in your "Trying" to make sure viable mid lane was the Refresh Plant Duration with her Ult.
That was on the PBE all the way up to the patch going live. BUT that part didnt go live.
You have no clue what Zyra mid needs.
You dont listen to Zyra Mid Mains.
