Yeah, I realized that after posting that AC would make the rotation "more AE," which defeats the purpose of a "more dynamic rotation" as a goal. But it'd need to be 40s to make it work right. That way, you do 2-3 AEs per minute (as opposed to 1 without and 4 with).

The devs could also tie a DoT or some other ability into DE that reinforces the idea of using DE every ~40 seconds, but I'm hesitant to think of "what" should be done considering the NIN's damage doesn't feel particularly awful despite looking awful (NIN damage is deceptive). The idea being that making it a requirement I feel would be beneficial. I don't like the concept of the rotation altering its priorities at all. Either way it's done, I'd prefer that over "You do 1, or 4, AEs per minute depending on having a WAR or not." This just alters the NIN too much on something outside their control in a way that isn't really interesting no matter which way you look at it.
