Berseker's Unleash button is a hassle, there's no point in turning the skill off.

Let Berserker automatically activate Unleash when pressing the skill button, rather than using 5 skills while in Vengeful Wrath to activate it. Increase Unleash's current overall damage but in return, reduce Berserker's HP every second when Unleash it activated so that we need to keep an eye when to turn on or off Unleash.
