Let me ask you something: Do you OWN the server?
2nd thing: you got what, 300, maybe 350 active players on the server?
I am not here very long, but have essentially happen to me quite few times, is one guy dropping shitload of mobs on my ass, while another is stunning me from a distance. I'm just trying to do daily quest, still not even on 76, I'm struggling. How do you expect me to stay on the server, when I have this shit done by someone I have no connection to, no clan enemy, never pked anyone who didn't try to PK me.. Like, I'm struggling to get to the higher levels where the fun is, but if someone (might as well be you, for all I care), is too scared to face a larger group of new players who grind their way to the top and potentially shift the balance of the server, then who is the pleb here? The people you prevent to get to the top, or you who are scared of a little competition? I'm not really concerned about exp, you get me one time, I don't come back to that spot, but if you drop my items I've been grinding for months to get, cuz I'm not a rich spoiled brat to get my daddy's card and swipe hard to be the best, then you are the true pleb here.
On the subject it self, I have no idea how true PVP and PK drops works, but I would remove mob drop for at least lvl 76- and maybe go for 76+. Or maybe remove it completely.
And before you trash talk me, I've played this game probably before you were even born (key word PROBABLY).
