I'm curious as to how many healers most guilds are bringing to each of these fights so far in MoP. Most of the time my guild gets by just fine with 2 healers (Druid/Pally) but some fights were kicking our ass until we had a dps swap spec (First fight in HoF the most obvious example). Currently we are having a tough time getting through the final tornado hallway phase of Blade Lord Ta'yak. I'm reluctant to bring in a 3rd healer because we have no problem healing through phase 1.
