So, after the patch, how goes it with Paladin?

500 potency? How exactly did you get to that number?

[eagledorf]

Swapping in and out takes 2 GCD. Assume that you would have done 2 steps of a Royal Authority combo in those 2 GCD.

A Royal Authority combo is (150+200+340). With slashing debuff, each GCD has an average potency of 253. Losing 2 of those GCD is 500 potency on average.

However, that's actually only true if you cancel the first two steps of the combo to stance dance. Cancelling mid-combo is an even bigger potency loss than 500 because you have to repeat the Fast Blade step. (Though it actually also depends how many times you stance dance. If you dance once and lose 2 GCD without cancelling a combo you lose only an average of 192/GCD since you lost two steps, but if you lose 6 you lose an average of 253 since you lost two full combos.)
