Well, for UW its not wise to go in large groups as you don't make much money off of it. I recommend dualing UW.
When I was in Fow we had a bonder and a healer. The bonder but enchantments and maintained them on everyone while I healed them.
Or sometimes we just had two healers.
If your healing with a bonder bring skills like dwaynas kiss, orison, word of healing. Also you'll want to bring Divine Boon. Also Heal Party helps alot to for when your whole party is being attacked.
When ever I played with two healers the healing was much harder. People took alot more damage without the bonds on them. You'd take pretty much a basic healing build for this i think.
And the morale of the story. Do FoW with a bonder and a healer.
