Post-BB paladin dual charge and dual weakness

74% mastery from ACB only takes effect when an elemantal charge is activated. ill link the video that shows this later.

Actually I refer to this screenshot

And yes he does not have elemental charge at this moment

PLEASE DO THIS!!!!!

I guess it's still main charge % + 12.5%(lightning charge) (which sucks...)
based on this video
[video=youtube;8If-JeOOuWU]http://www.youtube.com/watch?v=8If-JeOOuWU[/video]

his damage range is 11042~11747(with blessing armor activated), and his ACB lv is 12 (480%),
the ACB damage on blue wyvern(lv137 so no damage penalty) while blessing armor activated is around 105000

here is the math...
assumed blue wyvern PDrate is 10, with 800 WDEF, the original damage should be 105000/0.9 + 800 = 117467
the damage calculation of ACB should be 1.5(fire weak)*4.8(ACB)*x(dual charge)*11394(average damage) = 117467
which means x = 143% which is very close to 130%(fire charge) + 12.5(lightning charge) = 142.5%....
please someone proof me wrong XD...I really hope it is direct multiplication....
