I love(d) my prot paladins. In terms of world quests and pulls, they were borderline faceroll but you make it exciting by pulling things that make you look like you strapped a slab of bacon to your ass and ran through the local dog shelter's play yard. Dungeons were a bit rougher because they don't soak the damage like hunter pets do but it was definitely a fun group.

...that said, I've been on hiatus from WoW for a few months so I have no idea if they've changed things (read: broken things) in 7.2 that would make a notable difference.

The funny thing about Paladins is that they can never decide whether to nerf them or OP them, so you get the best and worst of the balance changes.

Good luck!
