Healing: depends on situation really, some fights it requires single target tank healing, than pally is the best job for that and DPS.. pretty much even imo.. but pally would need better gear to actually pull off some decent numbers
PVP wise.. i'd say druid... you possibly cant kill a druid 1 on 1.. its too hard.. and will make it harder in the next patch since ret is getting a small nerf
