After playing a couple of monks since they were released, I have come to the conclusion that wholeness of body is pretty horrible in its design. It doesn't synergize with the party and I can drink some cure serious pots to gain hp back alot quicker.
I would really like to see this changed to use the LoH mechanic (self use only of course). It has a cooldown and still cost's ki to use, so its not free unlimited healing. What it would do though is actually make the feat more useful in combat which is where it matters.
