Barbarian exploit found: Permanent furious charge
The bug is triggered when a Barbarian uses Furious Charge with any rune on it to charge through a cinematic and cancel the sequence immediately after. After the cinematic is cancelled, the Barbarian enters a never-ending charge state, applying the selected rune effect (be it life regen, fury generation, stun, etc.) and the damage as he/she runs through mobs.
The exploit persist if skills builds are changed but disappears once furious charge is cast for a second time.
