In 5E, Lore Bards who steal Aura of Vitality are better healers than almost any cleric. They still don't have the flexibility of the cleric (are less likely to have access to Speak With Dead/Death Ward/etc.) but they have their own perks like Bardic Inspiration, Hypnotic Pattern and Vicious Mockery. My experience with 5E is that it is possible to survive and thrive with a bard or druid in lieu of a cleric. (Theorycraft says it is even possible to survive and thrive with no magical healer at all, due to the Short Rest Healing mechanic and things like the Healer feat, but so far every party I've played with has had at least a druid in it.)
