Post-BB paladin dual charge and dual weakness

I am not sure if anyone already discussed this,
post-BB, if a mob is both holy and thunder weak,
it will take
150% * 150% more damage if dual charged as holy & thunder
or
only 150% more damage?

Thanks in advance

I'd assume normal damage because of how close they are in terms of damage.

125% Lighting x 135% Holy x 150% advantage = ~253% total damage
253% damage x (280% x 3 Blast) = ~2125% Blast damage (not factoring crits or instant kills)

200% Advanced Combo x 160% Enrage = 320% total damage
320% damage x (210% x 3 Brave Slash) = 2016% Brave Slash damage (Enrage limits to one target)

Without factoring other skills or effects in play, they are too close to give Paladins double advantage. I have did some math, but of course it's all in theory. At least for now you have some sort of answer be as though it may be temporary.
