Do I have to run the Optimizer for each spec?

Recently I have been playing my Druid, of course I play all four specs? when I run the Best in Bag Optimizer do I have to import my gear for each spec? or is it a one and done?


All you need to do is activate all your spec.'s to get them included for optimisation.

In Best-in-Bags, there is a list on the left that needs to have the spec. you play most at the top, to make sure that one gets taken into account.
