Your RAs should be balanced around the other Healers RAs usually. As there are a lot of things healers can get. As an aug healer with no instas to peel for yourself from the pac line you will want mitigation for when you scramble, ie high BOF to reduce incoming melee damage while you scramble and call for peels. dI is something you can kick on during the scramble. This will heal the smaller damage coming in from the BOF reduction, making it more effective than using it as an insta heal. You will also eventually want MOC to cast during chaos. Obviously moc 1 and 2 are useless unless it’s used on theur for petting or shams for disease etc. purge 2, lw1, tireless, BOF 2-3, dI 3 or better, perfect recovery 1-2, and moc will probably be your most used RAs.
Until you are higher realm rank you share these RA with your pac healer until you both are able to pick up all the toys. Moc 3 early on will help you free cast every 10 mins until you build RA for other toys.
