It boils down to preference, i prefer DET>crit>SS as the SS value is worthless on fights where you cant continual spam. Cure 1 crits are better than cure 2 normal casts. I think if you went full SS / full crit, the heals on paper are the same or 1hps different (looking into the subject). Don't be a sheep and do as you like! It boils down to more your skill as a healer.
