Oh, I know. But the problem is not in that. It's more in the robotic, typical job-form like way in which it is done. There are many ways to see if someone is good enough for the job. Out of all, the majority of the raiding guilds go for the way that most seems like you are applying for a job instead of for a friendly raid group that wants to progress in a game.
And sadly, I've tried. I don't know if I'm just unlucky, but I don't think it's very uncommon to have a raid group that focuses on WoW as a job rather than a game while still being serious enough. I tend to hear these nightmare stories all the time, and it's essentially what keeps me away from raiding again.
