Thanks everyone for the replies, and I have been persuaded to go with my 5 druid team. It sounds like it has the potential to be a very strong group for dealing with a lot of things. I think that if all have the correct spec, then they will be able to deal with anything, and I do like the idea of having my main healer and then a secondary off healer for those oh shit moments. Once again thanks everyone for the great posts, the reason I was thinking druids might not be able to handle the healing of heroics is that many people in my guild and friends have been telling me that they just might not be able to keep up with the huge blows that some mobs can deliver, however with an off healer that really should not matter nearly as much.

Thanks everyone, once again!
