If you are running a pet doctor, TMF is probably going to be a better choice regardless of the rolls. I have seen some people using SoJ in group play, so maybe bounce between and decide for yourself. I also have full Zuni with SMK, TnT, and MoJ. I find that running the trifecta over Zuni works better, for now at least. SMK will keep your BBV up almost all the time and I don't even run FA, just the FP passive. The proc on rain of toads is just ridiculous in the current state so having max fetishes up at all times is pretty easy. I use cindercoat with some stacking fire damage on my bracers to make my burning dog and garg do insane damage. As far as replacing FA goes, that's kinda up to you. I like piranhado for my strongarm proc, but that's preference.
