I'll be blunt. I've heard this argument my entire tenure in the game and the answer is the same - they're not going to alienate players by *forcing* players to play to your standard.

If they're clearing content, they're making the bar. There's harder content out there if you want to avoid them, stick to doing that content or stick to your static, if you have one. If you're doing roulettes - you roll the dice. Personally - I'm more concerned with poor attitudes than poor performances - and when I want to avoid both (And/or the DPS queue timer) I leveled up my trusts. I'll take the added dungeon time to avoid the stress when I don't feel like it. On that point - as long as Trusts exist, you're never going to be able to enforce any sort of bar to get people to pass in order to play this game. It may be time to make peace with that.

Content *has* gotten progressively more involved, anyone who's watching the new spike of WoW Streamers play the game can attest to that. And we still have people complaining about the typical pet peeves.

Honestly, there are exceptions to a lot of those complaints and more to be had. A tank that doesn't trust a group or isn't feeling like stressing themselves out will pull slower. A healer not confident in their ability to heal yet will not dps. And those two are the only ones who can judge when they're ready to push themselves. In dungeon content, who cares? If you're that concerned - party with friends and don't rely on randoms who won't always be on par.

Roulette Content as about as casual as you get in this game, so stressing out over it sounds more like a personal problem than a game problem. There are other ways of making in-game currency that don't involve other random people. It may be more worth your while to use them. I do, and I've learned to be much less stressed and judgmental for doing so.

Just be friendly and encourage players to push towards excellence as politely as you can, and learn a little patience on your own end. Use the alternatives available to you if you're not in the mood to tolerate it. I promise you it'll serve you well.
