Post-BB paladin dual charge and dual weakness

If that's the case then wow, dual charging is a useless bonus to Paladins. it would add about 6-10% more damage depending on weakness. In fact, I'm only aware of a small fraction of the game's mobs being dual weak. Those mobs being Road of Regret mobs (F/L), Road of Oblivion mobs (I/L), and Anego (H/L). I always thought Dual charging helped make a huge difference in damage. I guess they really aren't on par with Heroes on 1v1 (not counting bosses).
