Except I believe that DCNH is unreliable. It might be definitive but I don’t see it as constant.
And yes, it can be difficult to tell Duals from Conflictors sometimes. I find that it becomes 100% clear, though, after spending about ten minutes with a person.
Duals give me an impression of no conflict at all, while I will be going along with Conflictors, curious about them and hoping for the best with all my senses focused on them, and BAM a sudden punch to the teeth and where did that come from?
Duals can also produce shocks initially but they are mild and are easily overcome by my general admiration of them.
