Most who have played around with the class probably know this little trick. But, it's a good one to have, nonetheless.
If you are in Man Form with no wrath and are contemplating an attack on a camp with multiple mobs...try this simple trick.
1. Activate Ferocious Roar
2. Immediately switch to Bear Form and activate Rush skill.
3. Switch back to Man Form.
4. Wait for all mobs to get within 5m.
5. Use Biting Edge skill.
That simple process allows you to stun up to five (5) mobs in Man Form. It's a nice start to a fight in that situation, because you now have a couple seconds to fill your wrath while your opponents are knocked out. Ferocious Roar, which initially gave you the wrath to switch to Bear Form will, also, assist you in building wrath. Switch to Bear Form with full Morale and full Wrath...and enjoy the carnage.
