My group? I have no relation with the griefers you described, nor do I have an obligation to "police them". Do I blame you for the excessive behavior of pve griefers? No. Griefers are griefers, go talk with them.
Now, with good rules PA could have prevented that. With even better rules PA could have even allowed us to participate in this control. But PA mainly chose useless band aids.
Blame devs, blame griefers. But you have no right to blame all the decent pvpve players of this game, despite what you seem to think.
Devs in BDO could alleviate this by giving bonuses to group PvP ( XP-item drop amount) but they didn't. I will say though seeing thousands of guild decs go through in a 24 hour period by the same guilds is not missed but I will say they need to figure out a way to scratch the itch of PvPers ( Not red players) without running off their bread and butter spenders in the game.
They could have added the bounty ststem in the game giving rewards to those who volunteer for it on "SPECIFIC" servers versus bandit players, more open world equalized PvP gearing ( All dropped gear should have been nothing but PvP gear while boss and Blackstar was PvE gear).
BDO is too lop sided due to high dependency on RNG progression and not so well thought out dynamics of the game. I mean they put more thought and effort into getting people to buy " ass out" , big tit, high- heel costumes than on how they can get " EVERYONE" into enjoying PVP content and this is a real problem.
