1) Feral Faerie Fire becomes a core ability.
2) Brutal Impact increases duration and lowers cooldown of Bash. It swaps with Savage Fury, mostly to keep it out of the paws of anyone but Ferals.
3) Feral Faerie Fire replaced with the old Last Stand component of Berserk. But it's usable in both cat and bear forms.
4) Cat Berserk does not change. Bear Berserk goes back to Mangle hitting 3 targets, and since that isn't so useful on single targets, it also removes the 6 sec (untalented) cooldown of Mangle during the 15 sec duraton for some nice bear burst or threat generation. The Fear immunity is still intact.
