I agree that putting it on all of the tanks might be bad for their diversity, but then I can't think of many alternatives to add intrigue to the rotation.

Spam windows have proven a huge success on the other two tanks, so thinking of it from a developer standpoint, it makes sense to continue with it on DRK so that it's not just "Souleater spam".

The expansion isn't released yet and we already have dozens of threads nitpicking and criticising every little thing, when I am minded to just simply enjoy it. If I am capable of enjoying it on PLD then I probably will on DRK.
