A dual-focus PvP healing build, with destro/resto staves and 5/1/1 light armor preference, best suited for groups of five or more. Combines high-damage bursts and debuffs on the destro bar with sustained healing and support abilities on the resto bar, allowing for quick switches between solo-capable DPS and group-friendly heals. This build is especially flexible and surprisingly competent in most PvP situations, and can take down (or at least chip away at) even the tankiest targets while keeping you and your group effectively topped off.

Recommended DPS rotation is as follows. Note that the Purifying Light damage proc, to my knowledge, is also affected by damage done by projectiles cast PRIOR to its use, as long as those projectiles reach their target AFTER PL has been used. So to maximize your efficiency, make sure to cast Purifying Light after the first Dark Flare in a chain of casts, and repeat after each proc. ">>>" indicates a delayed-cast ability, while ">" indicates instant-cast. See here:

Dark Flare > (before DF hits the target) Purifying Light >>> Dark Flare > Aurora Javelin >>> Dark Flare (and by now, PL should proc) >>> Dark Flare > Purifying Light >>> Dark Flare >>> etc. >>>>>> (once the target is below 35-45% health) Purifying Light > Radiant Glory > Radiant Glory > Purifying Light > Radiant Glory >>>>>> etc.
