My assumption is that the heal nerf is designed to keep heroic content from becoming trivial. Changes I think that should be made to berserker heals. Battle Frenzy: Increase the base to 6% per hit. Berserk (SF Ward): 0.5% damage reduction per AA point while berserk is up. Blood Rage: T9 Master should provide a 1500 HP buff for 4 seconds, with AA the HP buff would increase to 2250. Persevere: 20% heal, leave it at 30 seconds. Unyielding Will: Change to always up buff, 5 minute recast, castable out of combat only. Vision of Madness: Double the value of the heal. This isn't what I really want, but keeps the general idea of the abilities, helps several of them scale and transition between solo, heroic, and raiding.
