Yes. Every DNP I've fought has been tenacious, whether near their capital or near our own.
This has not been my experience. I have witnessed DNP members engage in sealclubbing and grief tactics, such as ASSASSIN and darkjoker. Those wreches qualify as antisocial blowhards, not honorable by any means. Skilled in pvp, certainly. If that's all that matters to be considered "honorable" then your definition of the word needs work. It's not what you can do, it's how you do it that counts.
