Hey everyone. I never realized this before (maybe I was spoiled from playing my 101 warrior), but do different classes have different number of champions obtainable at 101? My warrior has 3, but on my paladin it seems the quest to get the next one requires 102. Also, I have a DK and Hunter...

My followers have reached rare status and can recieve equipment. Is there equipment available for your followers to use or is it just a wash now?
