Phase 3 Feral Cat DPS for BT/Hyjal (bear offtanking is a separate gear set). Wolfshead Helm stays BiS; Thunderheart Harness covers the set bonuses. Pillar of Ferocity from Archimonde is the raid staff goal. Stack Agility / AP / hit / expertise / crit — DST and Madness of the Betrayer are the trinket chase.
Powershift with Wolfshead, never let Savage Roar / Slice-equivalent uptime drop (Mangle / Shred / Bite cycle), and swap to bear only when assigned. Keep Omen of Clarity procs flowing into Shreds.
