RECENTLY, If I see a DW cap, it is in O-15, why? because all their enemies (Harvies, 522(in the past), etc) are MOSTLY in caps too.
I have seen some weird and odd things happen with DW recruits (Some recruit,,,were, in short and simple, relying too much on their caps) in the past, but it seems to have been solved.
Again, as I said earlier, Just mix yourself even more. Dare to communicate with us, even when there is no need for it.
