Yes I can see why you say this. Holy priests are slightly more PvE specced healers than PvP. Druid is almost better for PvP as a healing companion since he can morph out of sheep, snares etc. and just kinda run around in catform casting regens. There is always Psychic Scream but yeah, pallys have a little more room. Plus Fade doesn't exactly do wonders in Wsg. But then, PWS every other second (especially if you're Holy/Dis) is a godsend. Throw one up on you, teamate and then a regen or group heal and you're good again. But yes, I hear ya one sheep and thats it for the priest. Just arguing with myself out loud
