The changes to the rogue system really made things worse. Before people cared about their levels trying to get gear and rank, but now you have people maxed out pub stomping in packs. They don't have to play careful anymore, there's no decision to be made, especially now when there's basically no penalty. Only people now penalized are those who didn't gear quickly via whatever means found early. Those people are just trying to get some ranks for gear and progression but now locked out.
Someone said earlier the DZ is pretty much dead for better choice of words, and that's true. People are fed up already. So this needs to be fixed, fast, before people leave for good. And griefers should want this fixed because soon enough they won't have anyone to grief anymore. Massive needs to make a PVP zone for these people, and see how many people actually go there that "just want to PVP". My guess is not many, because it's much more fun to grief, thus that's their main goal.
So, make a dedicated PVP Zone, then revert the rogue changes they made and make them actually much harsher somehow. Make going rogue in the DZ a true risk reward decision, like a "rogue sickness" which starts to stack reducing your stats for a period of time as well as the XP/credit loss.
Besides, it was infinitely more fun before when someone went rogue, everyone chased them down, and you tried to run. It was a bigger deal. Now when people see you're rogue they run away because they know there's good odds you're geared and that you have 3 more griefers with you. In some cases you have coordinated groups, so 8 people teaming up, shooting the 1 or 2 players in the back farming mobs for gear/rank. Not to mention the inherent flaw which is rogues pick their battles. Combine that with how quick people melt, or how tanky some people are, and yeah, it's a mess.
Such a great concept in a shooter and such a great game, but it's not going to last if things don't change.
