I don't know about you guys but I find Zyra is way too powerful currently in important aspects of the game. Every game I've lost since she arrived is when my team doesn't have her while the opp team has. She turns team fights upside down. Sure we can go straight for her but she just needs to spam her abilities once during team battles and step back. And unless you can roflstomp her easily, dueling her 1v1 sucks with her passive. With her roots harassing her can be very difficult as well with it passing through mobs.
These are my opinions/experiences with her. How do you guys find her?
