From the perspective of a 700 gs gearlet just venturing into BDO PvP, I think the new NW changes are great for newer guilds. My guild recently started tackling NWs solo, and this new system is helping us get up to speed with macro gameplay along with everyone else.
I wasn't a fan of the 1 hour Node War at first but this last weeks seige lasted 4 hours. I will take a single hour of enjoyable large-scale PvP over 4 hours of mindless running through the desert.
