Do yourself a favor.... ignore ^ and ^^ and ^^^.
Just because they have a high skill cap for healing, doesn't mean they are bad at all. Just because they can't rez shitters non stop in 5 mans doesn't mean they are bad.
On the competitive raiding scene, is what you want to look at. Why? You don't judge a class by the people who suck at it. You want to know the skill cap and performance range based off of the best of the best. So let's look at that for a second.
**This takes into account the top healers across all major Vanilla Servers within the last 30 days**
Boss fight average is calculated by taking the 5 best performing(for the player) encounters out of the last 6 attended. So no fluke numbers.
MC:
#4 Healer is a druid from our server. So is #8 and #10. So top 10 has 3 priest, 3 druid, 3 shammy, 1 pally.

2 of the top 3, no pally in top 10:

Druid top healer
http://realmplayers.com/RaidStats/Ranki ... &realm=AllBWL:
Top healer is a druid using a mix of T3/T2. #7 is a druid using T2 and less gear.
http://realmplayers.com/RaidStats/Ranki ... &realm=AllAQ40: (no optional)
Top 2 healers are druids with end game gear. 4 druids in the top 11.

Realm Player data is limited due to most Naxx raiders have moved to Nost, this is from Agent Crusade.
http://realmplayers.com/RaidStats/Ranki ... &realm=AllWhy are they least played? Perhaps they lose appeal having to look at an animal while leveling, or have not "I messed up bad, get out of jail free ability". Can't tell you. I love playing my druid, when I'm not tanking and look forward to when I can one day do some raid healing. "High skill cap" = reserved for the best.
Don't respond with, well they are geared, so are their competition on these stats.
