We in particular don't rotate because we don't have the people; we either have our core 10, some people that aren't always on (friends/ex raiders who are casual now) or just people who aren't geared enough (fresh 90s, etc.). I've wanted to press the issue of recruiting rotational people, but the idea seems like a foreign concept to the other officers perhaps due to bad past experiences; as I previously said I recall a hunter from a prior guild being kicked due to volunteering to be rotated out for fights where he didn't need any loot, but expecting/demanding to be there for bosses he needed loot from.
Honestly I can't answer that question because I've been rotated out when I was mainspec DPS (including a guild's first Nefarian kill in T11
), and yeah it sucked but I was okay with it after a while, but I think there's a fine line between everyone knowing "It's okay to sit out for a boss if you don't need anything" compared to the perception that if you're sat, it's because you're being replaced or because you screwed up. Our guild, though not my decision as I've only recently been an officer, has usually given the perception that if you were asked to sit out for a fight it was because you were underperforming and we didn't want to wipe on a "farm" boss, not because you didn't need anything and someone else did, and chances are you weren't coming back in the raid that night (or for the rest of the week). So that might be why I have such a bad view of rotation/standby/bench, because in my guild it means "We're bringing in someone better than you to kill this boss". I also think it's the perception that you need to be there for every boss because you're a "core raider", either for a drop that might be useful or just the VP.
