A new patch is now live in Heroes of the Storm, updating Blizzard's MOBA with balance changes and bug fixes, as well as Chromie, the game's newest hero (it's like deja vu!). This post has all the details on all the changes, and this post introduces Chromie and her abilities, and here's a trailer with a look. Here's more:

At first glance, Chromie is a charismatic but somewhat forgetful gnome, constantly distracted and intrigued by the world around her. But don’t let her appearance fool you. This seemingly precocious gnome’s true form is that of Chronormu, a powerful Bronze Dragon capable of bending time to its will, eternally tasked with maintaining the balance of infinite timelines by any means necessary. Sensing a disturbance of the greatest proportion in a brand new world, Chromie now makes her first foray into the Nexus… or is it her second foray? Or third? There’s really no telling. It’s so hard to keep track!
