That said Holy can be one of the best swing healers but as I alluded its really comp dependent. If for instance you have a leather and avoidance (warrior) tank, or 2 leather tanks or something, and 0-1 plate DPS, you'll probably be a great swing healer (especially if your caster team is cloth heavy).
If you have like 2 plate tanks or 1-2 plate DPS or better yet combo of both and you have only 1-2 cloth users, your priest is better off swinging. But swing healing as a priest can be a PITA, coming from someone who did so in an alt run last tier.
