Paladin, Shaman, Druid: Hybrid Flexibility + Survivability. I enjoy being able to specialize in a role, but I also like flexibility in switching between roles. I enjoyed having healing spells even if I was not healing in an encounter. What I really liked about these three classes were their many "when crap hits the fan" options that were useful in groups and solo play. In numerous Vanilla dungeons and raids, I used my hybrid classes to pick up the slack of poorly played "pure" classes, which at the time were defined as all the other classes. Vanilla endgame, talents and itemization for hybrids were abysmal. But also, perhaps more importantly, I loved the lore that surrounds the paladin, shaman, and druid classes.
