if you are having trouble with your heals being low try making a physick + embrace macro. it basically serves as a SCH version of c2 but with hate split between you and the fairy and low mp cost you are alot more free to spam it
on the subject of dps, if you wish to DPS comfortably get used to using stoneskin instead of adlo, its mp cost is a bit lower and it is not affected by cleric stance. also learn to rotate your fairies cool downs. once you hit lvl 50 you also have access to lustrate which is not affected by cleric stance.
in a non speed run environment, i dps exclusively thru entire dungeons without ever casting a single adlo or physick. properly timed lustrates and making sure to always keep stoneskin up on my tank allows me to never leave cleric stance.
with cool downs and proper mitigation with eye and virus your fairy can solo heal every single 4 man encounter in the game
