But people who join groups that explicitly advertize e.g. full zerk, minimum achievement points, ping gear, experienced only, no rangers, no necros, or similar stuff will obviously kick people who join but don’t meet those criteria. As they should, right?
Advertising criteria like that for a PUG is passively aggresive. It’s no different from excluding that one kid in the school yard from the lunchtime football game because they happened to drop a pass or fumble the ball the previous game. Is ArenaNet obligated to stop this? No. Will it continue to happen in every MMO? Absolutely. I have no illusions that this behavior will magically cease. However, I still think it’s a stupid way to play games. The main reason I left WoW was that you were pretty much forced to adopt that attitude in PUGs as well as organized groups if you wanted to enjoy the game. My experience in GW2 so far is that there is no such need. That may change when I get into higher level fractals, but so far I haven’t encountered anything that couldn’t be overcome through the slightest bit of persistence.
If it was a reverse situation where someone formed a play-how-you-want, all builds accepted group and somebody joined in full zerk gear and then started constantly complaining about poor group dps, complaining about the ranger/necro in the party, and calling everyone noobs and complaining about inexperienced play, he would also likely be kicked, right? As he should. He simply joined the group with improper expectations.
It’s a game. I don’t want to play with a bunch of cry babies and drama queens. I’ve spent years training my kids to quit behaving like that, and I don’t want to educate someone else’s kids in game. Kicking such a player would have nothing to do with how they play and everything to do with dragging down everyone else’s mood by acting like jerks.
The OP’s assumption that kicking players who don’t meet advertised group criteria is a form of aggression is incorrect. People joining such a group when they don’t meet the criteria are obviously the ones who are being “aggressive” since they are simply annoying or interfering with others who are trying to play how they want.
The act of kicking may not be aggressive, but the advertisement in and of itself was already aggressive. That having been said, I personally don’t see why anyone who didn’t want to meet those criteria would even join such a group. I would chalk it up to ignorance. Someone who doesn’t even know what “zerk gear” or “APs” are may not even realize that they are failing to live up to certain criteria.
I have no desire to run dungeons with PUGs right now, but if I did, I would probably use those advertisements to filter out the groups that I don’t want to join. I prefer unexpected adventures to repeatedly running an instance at top speed exclusively for the sake of farming materials and gold. To each their own, I guess.
