Unlike many here I started with a Shaman, and then made a druid as my first alt (that I got to 60). Now that I have a 60 Shaman and a 60 Druid, I regularly switch between the two for raids. Some nights we have three Shaman already, and our Clerics are begging for PotG. Other nights we're low on Shaman, or maybe we have some of both Druids and Shaman, but we need healers so I play my Shaman (Druids aren't bad healers, but Torpor > Nature's Touch).

But my point is that, in my (non-zerg) guild we don't always have one of every class at 60, and there are absolutely times (around half, though I don't measure it) where I choose to play my 60 Druid over my 60 Shaman.
