Slight point of contention. Rejuv will get the same HPS increase with crit as haste, but the overall healing of the spell will increase with crit and will not through haste until that extra tick. It's an important difference when considering HPM.
In theory though, HPS does not matter as much as HPM on cata fights for hots other than LB, again implying that crit is more useful between those gaps for hots.
