My biggest issue with Unchained Monk is Wholeness of Body ability.
2 Ki points, as a standard action to heal as a barely stronger CLW. This ability was insult with the base Pathfinder monk, mediocre in 3.0 and 3.5, and working as intended in AD&D 2nd edition (implying anything in the 2nd edition was working as intended after all), it was copy of Paladin Lay on Hands ability.
So more then 10 years and 4 editions later, this ability is still mediocre, while Paladin gained useful Lay on Hand, usable as a swift action, and further empowered with mercies.
Was making this ability cost 1 Ki point and make it usable as a standard action asking too much for such overpowered class as monk?
