This here is the one of the main ways 25s will have an advantage over 10s. While it *is* harder to get 25 people to follow instructions, it's also not as big of an impact of 1/25 screws up and dies (unless it's a tank). Note I'm not trying to say this means 25s will be easier overall, I'm just saying it contributes to evening the playing field.

In a lot of discussions I've had with 25-manners who are angry about the issue, the common theme is that they cannot imagine how a 25-man could be easier. All of them cite examples like 25-man LK versus 10-man LK. None of them seem to want to consider the fact that in Wrath, 25-mans were balanced to be less forgiving. We simply don't know how 25-mans are going to balanced in Cataclysm in relation to 10-mans.

This is also the reason I like 10-mans better. Call me a little selfish, but whenever I find myself in a 25-man I feel like I'm participating in a massive spam fest, and that I could run over and jump off the cliff and no one would know the difference.

My personal contribution to a 10-man is much greater. I feel like I'm actually part of a team working together, and not a faceless member of an army that's indistinguishable from the others.
