Retribution. This is what every paladin begins as. No shield to hide behind. Just a big two-handed weapon slung on your back and grim determination as your guide. And, sadly, the spec that took the longest to become completely viable.
It's been a hard road for the retribution paladin. In classic era, you only used retribution to level up and then you were expected to heal or play blessing-bot for raids. In the days of Burning Crusade, retribution was a little better and could be okay if you stacked your raid the right way. However, they'd rather you be the adds tank or heal. Then Wrath hit and retribution came into its own... or should I say 'pwn' (bad joke, but absolutely true if you remember early Wrath). After some balancing, retuning, and all of those other euphamisms for 'nerf,' we're a still a fairly decent force along with the rest of the pack. Let's take a deeper look into the good, the bad, and the ugly of the ret pally.
