Just a quick thought that popped into my head, what if in the upcoming expansion, instead of Beast Mastery getting Exotic Pets and leaving out the other specs (spec now I guess) but instead let both BM and Survival tame every type of animal and just give BEast Mastery access to either an Exotic Ability, Exotic Aura, or both and the on top of that a few more special tome required class quest animal families on top of the tracking quests a la Gara
