Healing classes on MoP

Hello friends of frostwolf, and first of all, thank you for your time.

I'm starting to play on this server with a bunch of friends and i have a question about MoP healing, regarding specially the fact that we are in a private server and there is always some bugs, the question is, which class develops well in therms of being functional? I mean, not having that much of bugs and can do well both in PvE or PvP.

I appreciate your support, and again, thank you so much, xoxo <3

resto shammy best aoe healer for pve and its good at pvp :)

Resto druid makes the most fun for me :)

pve : shaman>druid>monk>priest>pal
pvp : monk>shaman=druid>pal=priest

For me monk is working really well, Mana is no issue at all because of mana tea (easy to keep 15+ stacks up all the time) and the healing is quite high aswell i'd say. (But I still think 4p priest t15 will outheal anything and anyone.
