Pretty beaten horse here, so keeping it short and sweet:
what the title says.
For ember, a little more survivability would be nice... As her firequake augment is rather hard to use at sorties, with a full damage setup. Her accelerant works as a stun, yeah... But I need to spam it every 3-5 seconds, and it doesn't work on important units. Not fun for gameplay. There are many existing suggestions/ideas of how Ember's survivability can be improved, so I won't be specific.
