MMORPG: Why can't we have nice things?

Let's talk about "elitism" or certain traits about elitism. It's a topic that many people who just want to enjoy the game have to deal with at one point in their life, sometimes on a weekly basis.

I've been thinking of coming back to Final Fantasy XIV: A Realm Reborn lately to enjoy the game. My character is near end-game dungeons and I think my first worries is the community state. To me, playing the game how I want is more important than getting results. I can't deny that a lot of people play the game to farm the hell out of it, to become the best player ever or to have the more hardcore guild, of course there are other reasons.

I play the game for fun: Is my first thought, this is so far true; always been. Now, the definition of fun is slippery, it could have a different definition, even if at the core they could be wrong. However, playing for fun means that regardless of the struggle my team goes through, we'll remain as civil as possible, or maybe sass a bit, throw a punch or two to blow steam but never go full retard on a team mate.

My problem with srs business people is that they don't leave the party, they stick there like an annoying stain filling the chat with vitrol on how much X or Y player sucks. Why oh why can't he keep aggro? I'm a healer I shouldn't overwork myself! (btw I believe healers in FFXIV have the shortest temper, they want everything easy I guess). Yapping yapping, annoying your team mates in group.

Then there's captain hindsight who won't shut up about a thing.

So, no matter what you do, there's always THAT guy who you get stuck with through all the way in a party. They won't give any advice, they won't shut up, they just want to finish the dungeon, get their commendation (lol), and hope that whatever item he wants drops. (everyone, GREED EVERYTHING)

It brings me to the question, why can't we have nice things in MMOs? It's so... tiresome dealing with people's sense of elitism, and sometimes entitlement depending on the issue.
