Well, we have the official teaser for Morello's upcoming nature mage. I'm even more interested to see her kit after reading "planting seeds on the battlefield that spring to life" - sounds prickly.
"Sometimes the most dangerous predators in the wild are the ones you’d never expect – even the vegetation in Valoran! Zyra, mysterious and alluring, is one powerful plant that is poised and ready to unleash nature’s fury on the League of Legends.
As fierce as she is relentless, Zyra uses the deadly vines and wild overgrowth of the Plague Lands as her weapons, planting seeds on the battlefield that spring to life into powerful allies. Are you the type that takes great joy in laughing maniacally as the thorns rise up around your foes, shredding them to pieces with the power of nature itself? If so, you’ll go wild for Zyra, Rise of the Thorns."
