I found something fascinating in the Dynamis proc system that I've never seen talked about before. I was switching between JA proc time nightmare mobs in Qufim.
I got there early and slammed JA's on a mob before realizing I was early. So I disengaged and waited. What was fascinating is that as soon as the time changed into the JA window, it proc'd with no activity.
Not that it benefits anything knowing this. Just mechanical curiosity of how the game registers procs. Is it a debuff that applies always but only activates terror/1hr dispel during a time window?
I'm just surprised SE went with something so intricate.
