BM with the 4-set bonus takes a bigger dump on the other two specs than before. MM will still be a shitball spec even after 5.1 with the 4-set bonus. The problem with Surv and (especially) MM is that the specs lack damage. Surv is only good in massive AOE gimmick fights but lacks good single target damage. MM just lacks in everything (AOE and single target). The spec will be bad until Blizz reworks it and/or gives it some solid damage buffs. We'll see though, maybe Blizz will surprise us lol.
