So far i like the update but please make barbarians less dependant on buffs and add some dynamics:
- Improve Overwhelming Strength
- Make Berserk something like 15 secs durations and 40secs cooldown
- Change Thirst for Blood to an activable spell like Recharged Arrow
- Lower duration and cooldown of Unstoppable Madness
- Lower mana costs

I leave the balancing to Ngd, but i think this is needed to make barbarians gameplay more enjoyable.
