Bard or Ranger for a 4 man group?

[Tenlaar]

Bard/monk/chanter/shaman is absolutely the right group. What makes the shaman a better healer than the druid is the combo of his slightly better than enchanter slows and his ability to canni to have higher mana regen. Shaman also saves the enchanter mana and time by handling slows. With a bard to add his hp regen for canni, mana song, and clarity, a shaman can heal circles around a druid.
