This is such a good point. If you are a high-quality player, and you know you are good, (never die in fire, never wipe the raid, top the meters/keep your assignments alive), it can be an exercise in frustration to raid with a bunch of nice people who mess up a lot. Conversely, you can play with 24 other people who rarely make mistakes, and they are a bunch of dillholes, and that's not really that fun either.

I think that's a great goal to aspire to, in terms of trying to help your guild get a little bit more serious. There are a bunch of people like that in my guild (who are a bunch of really awesome people I enjoy raiding and playing wow with). We end up carrying some people, as we are not a realm #1 type guild, but those of us in my guild that are high-end players prefer the more mature atmosphere (with slightly less progression) as opposed to the top guilds on my server that generally are a bunch of immature jerks.

To the OP, being an elitist jerk isn't a bad thing sometimes. Naming names and pointing fingers can actually work to your advantage - a virtual kick in the rear will get some people to focus harder and perform better. Being a taskmaster and railing on people every week won't work, but if someone isn't playing up to their potential, it can be a temporary boost to their skill score. But if people consistently die or do things to wipe the raid, then that's just who they are. You are then put in the unfortunate position of accepting sub-par gameplay from your teammates, or finding another group of people to raid with. That's a tough spot for anyone to be in, but it is a position that many players likely find themselves in, with how dynamic the game and guilds can be.
