What Burning Crusade were you playing? Attunements led to guild poaching and every guild below, like, the top 3 (at best) on your server being stuck in a revolving door that was unable to move forward.
Lemme guess. You were in one of those poach guilds to have that kind of view on what was a terrible raid design system.

Teamwork? You're joking, right. People would do it once, maybe do it a couple of other times, and then the next people after that they'd say "Nope, not doin it again, go f&*^ yourself". I literally had to guilt trip a tank in my own guild by offering him gold to tank Shadow Labs. He felt awful. I had been looking for a group for that dungeon by that point for two WEEKS.
