Encounters I had with them were on neutral/allied ships and I think all were in Gallia so I can't really judge them for combat but RP.
They are doing friendly, although sometimes not deeply immersive (not like this community is overall hard RP one), but still pleasant RP. Unlike another Corsair player faction that was coming to Gallia and I had to deal with, DTR guys didn't run to the nearest dock point as soon as I mentioned that I check if they have a license for goods they brought, what started, I believe, mutually beneficial and enjoyable relations between DTR and Gallic lawful playerbases.
Hope you will not burn out and stay around for long
