This worries me. I have been reading the Druid Fourms here and on the WoW website and it seems that a lot of Druids HAve 3 or more sets. I want to Know... Why? Surely If you are spec'ed to heal then you should only heal in a group... or If you are feral to only Tank or DPS in a group. I don't see much point in carrying round 4 sets of gear just so you can be ok at the job you are no good at, and cr&ppy at the job you spec'ed!
Can someone clarify why some Druids do this? Is it really that important in end game?
