When I heal, I also use guardian affinity but can deal upwards of 90k+ DPS. What I do is make sure I HoT up the tank (lifebloom, rejuvenation, rejuvenation), efflorescence, and then start to do some DPS. Moonfire, sunfire. Bear form, mangle, thrash, cat form, swipe x2, and then heal again if need be, otherwise, I repeat the rotation from bear form. Reapply moonfire/sunfire as necessary. There are many methods to DPS as resto but I feel like this is just my style. Other forms include using solar wrath on single targets and lunar strike on multiple targets and to starsurge when you can or
