Ive been enjoying healing in a party on my priest, but soloing on him is a nightmare.
You literally just PW:S yourself on CD, cast SW:P, and then wand.
This is terrible for mana efficiency. Shield is only for emergency damage stoppages and for ensuring you get spells off that can get interrupted. And you need more damage output from your initial burst. Nuke a couple times to open, finish with pain since it's an instant spell, and THEN wand. Wanding at the end, of course, is important to take advantage of the 5 second rule.
