Fun fact: On fights where you're fighting for HPS (like Sha/nazgrim etc, not a lot going on), this means that a lesser geared disc priest will often be able to keep up with a better geared, as their absorbs will be used up first, and the better geared disc risks their absorb timers run out before they get used.
