I have leveled pretty much every class to at least 70, most of them are 85+, but no matter what, there's no class that can match the Paladin class, imo. Sometimes I get random urges to play other classes or Blizzard added a new mechanic to another class that's totally awesome, but no matter what, I too always end up back with my Paladin. Because it's nostalgic, but also because it's still the number 1 class for me.
