I use Mend Condition, because I can use it to heal the tank while inside SF. The only time you'll be hit with conditions on a SF run is in GF, and even there, it's just a little bleeding. ;P
Eh, I suspose by that logic, I should use Orision, and not Healing Touch. Meh.
Theres quite a few skills that I see pront monks bringing to SF, but I just don't feel have a good use. RoF for starters. With the amount of damage the tank is taking after Barrier+Bond+whatever armors, the odds of RoF healing for anything substantial are slim. Ageis, eh, the tank should have plenty block stances of his own, which can be kept up more often than Ageis, same goes for Guardian.
Once inside, how often do you see people get physicaly hit? Almost never, and thats only when they agro ahead of the tank. They rarely hold the agro. I find bonding everyone an exercise in futility, since they're just walking targets for enchant strips.
