Zyra's still awful and you know it Riot.
Even with these so called AI changes, which aren't even relevant enough to notice. She's still one of the worst champions in the game.
She's ganked too easily, her spells have a huge delay to both its channeling and Zyra's movement. She's less than 1000 health at level 8. WTF? She's slow as hell. As are her spells. Her mana costs are absurd. Her passive is absolute trash and you know it. I've seen Rioters posting acknowledging this (Meddler)
Compare her to Casseopia, Viktor, Heimerdinger, freaking Azir. Whatever she was nerfed on release for needs to be reverted because I'm pretty sure there are champions out there right now that do exactly what she does, and better.
Is buffing her really that scary Riot? This squishy weed you call a champion, who feeds the enemy team gold if they're competent enough to lazily sidestep to the right? Give me my plant wizard!!
