So how will this beauty differ from Carlotta? All we know about her is that she's glacio and relies on heavy attacks, right?

I've been thinking of pulling Carlotta next patch and giving her static mist. But I don't have Zhezhi and am not crazy about pulling her. However if Iuno is Galbrena's BiS and she fulfills a similar role to Carly, I'd go for that in a heartbeat.
