..... if Riot actually implements decent AI for her plants. I mean it's 2017 and plants still won't shoot champions you auto attacked, they won't shoot champions who are actively attacking you, they randomly stop shooting enemy champions next to them, they have wonky targeting AI and often stop shooting at all. Plant attack speed is 0.8 on paper but ingame you're lucky if they shoot once every second lol.
If Riot wants to push Zyra towards a plant control mage instead of a generic aoe burst mage they really got to step up their AI coding. After that maybe they can actually make Zyra a mid laner as they intended her to be.
