It is a good rule of thumb for paladins.
1. If only a small amount of people complain about it, it's probably disgustingly underpowered.
2. If a moderate amount of people complain about it, it's probably under powered.
3. If a large amount of people complain about it, it's probably middle ground
4. If almost every complains about it, it's probably top 3.
5. If everyone even paladin's complain about it, you're probably playing cataclysm again and no one wants to play with it.
