Personally I love my druid for AOE healing in random BGs, but resto Shaman are fantastic PVP healers, as well as holy pallys. Not sure about monks but I assume they are good as well. Disc is good but Prayer of Healing isn't fantastic unless the majority of that group are close enough to receive the healing, but you can DPS and shields are always fantastic in PVP. Never enjoyed holy priest in BGs but they really aren't that much different from Druids and I love my druid in BGs, so they may be alright.
