Zyra would be a great mid or support if...
Her health bar wasn't the worst thing in the world. She is basically one of the squishiest champions ever right next to
. She has good damage and stupid CC. Its alright if you are immobile but if moving forward means you might get hit by insert mid laners poke ability. Resulting in half-healthing you, regardless if they are fed or not. That's a problem with Zyra's base stats. Its pretty sad that Zyra must buy 2 hp items to be on par with the amount of HP an ADC or Assassin has.
