Sometimes I think that if Gevlon did not exist, it would be necessary to invent him.
His latest brainwave is a mod that kicks and blacklists people from the Wintergrasp raid. Basically, if he or other mod users see people leeching or being stupid, they can kick them out from the raid, preventing them from gaining much of the rewards that the people in the raid get.
The thing is that for as long as PvP has had rewards, there have been leechers. People who sit in the Battleground doing nothing, essentially forcing their team to play at a disadvantage, while racking up the rewards that the rest of the team earns. Because the other players cannot impose consequences for negative behaviour, that negative behaviour flourishes. Automatic detection of negative behavior hasn't really helped.
What's interesting is that in the PvE implementation of automatic group creation, there is a mechanism to allow players to punish negative behavior: Vote-kicks. The group can vote to kick a player from the group and get a new player. All of a sudden, behavior that reduces the chances of success has consequences.
And I think that by and large vote-kicking, or the threat of being vote-kicked, has worked. There is far less obvious leeching in dungeons than in PvP.1
Gevlon's mod is essentially a vote-kick system for Wintergrasp, albeit with only one vote.
It begs the question: would PvP battlegrounds benefit from a vote-kick system like the one the Dungeon Finder has? Automatic detection of negative behaviour can usually be outwitted, but I think it's fairly obvious to the entire team when one person is slacking.
The sad truth is that when there are no consequences for bad behaviour, people often behave badly. There have been no consequences in PvP for a long while, and maybe it is time there should be.
1. We can debate about people doing low dps in random dungeons another time. To me, at least they're trying to hit the mobs, even if they aren't very effective. It's much better than them sitting at the front of the instance leeching xp and loot.
