I've noticed this quite a lot recently, more and more people are doing it, all i can say is its just pathetic play the game or leave and go do somthing else, you should be playing for entertainment not to grind you're 176th generation, just remove heirloomed items or make it so theres a 2week cooldown between retirement.
For those trying to defend this behaviour, there is a difference between playing even with crap gear, you may not be doing much for the team but you're doing something, these people have no intention of helping the team and 1 player can make all the difference in this mod, they run in alone against 10 people swing there weapon a couple of times maybe get a kill cos the first person they run into is low lvl, but theres no intent on getting a kill, their intent is to die as quickly as they can and thats what makes the difference.
A list of rules would be great in the announcement section supplied and posted by the admins.
Players like these make me regret spending hours of my time making a list so they could see what they can get by leeching, spending my time helping others even though my characters are only gen1 and have no heirloomed items.
