I will tell it straight up. Helena is improperly scaled and has so much armor and HP it's unreasonable and an utter waste of time once you're already gold tier. I can kill ursoth 2-3 times in the time spent with Helena. Mages aren't supposed to be tanks and she has more hp than elite bosses with no drops and bad points. I rage quit and hope I don't run into her on another toon. I don't know why devs think there's nothing wrong with her.
