You'd think that without resolve we would be given a stronger survival kit for just leveling alone. The traits for the Brewmaster of course has yet been revealed but then again, shouldn't we at least be decent without it? I'd suggest they they either:
Bake the tier 16 4pc set bonus into baseline Purifying Brew so we have a somewhat controllable healing or
Make Gift of the Ox generate healing charges (with a limit) we can use at will. Otherwise I have a hard time seeing how the Brewmaster is going to eligible for tanking at all and entirely impossible to use for new people due to the stagger-skill cap required.
