Check out this pic below depicting how people with different points of view may look at a water glass.
How would these different points of view translate to a raid? Perhaps a raid that is struggling or wiping on a specific encounter?
Optimist: We are clearly making progress! We're getting better!
Pessimist: OMG how can we be so terribad? We suck.
Realist: This raid group cannot complete this encounter at this point in time.
Idealist: One day soon we will work together in perfect harmony and take down this boss.
Capitalist: I'm just here for the loot.
Communist: We are all equally to blame for this fail.
Conspiracist: Blizz made this boss harder because they are trying to extend the period of time we have to wait for Icecrown.
Sexist: We can't do hard mode X with these terrible girls in raid.
Nihilist: We shouldn't get so upset over computer pixels.
Opportunist: This sucks, but at least this is good blog post material.
I think part of what complicates raiding is that you are bringing together 10 or 25 different people with distinctly different ways of looking at things. I think even in any normal guild, these different points of view can cause a bit of drama or angst. Perhaps if guild/raid leaders can recognize this, and think about what point of view their specific raiders may hold, it may help them better understand any sort of drama that may come up.
Anyways, bloggers... opportunists? Us? Nowai! ;)
