People really need to take a step back and decide what "elitist" means since it has become such a loaded term.
To most it means people that spend time theorycrafting, look for the absolutely the best rotation, and min-max everything. Most likely in a top end progression FC.
For some it seems to mean anyone who actually cares about how well they do their job.

If elitist means feeling that i shouldn't be carried though content and caring about how my DPS stacks up against par for the job I am playing then I guess I am guilty as charged.
BUT the truth is that I am not an elitist. I have played other MMOs where that name (the positive side of the term not the negative side) would apply to me so I definitely know the difference.
Regardless of how you play the game you should care about whether you play your job well or not.

You look at a tank and if he doesn't have the HPs or can't keep agro he isn't doing his job (even though if we could do a DPS check it may be because the DPS is just awesome and he can't keep hate).
You look at a healer and if people are dieing, they are dieing, detrimentals aren't being cleansed, or they are running out of MP then they aren't doing their job.
But god forbid if I ever mention in party chat that mobs seem to be taking a long time to die. HOW DARE I.
If the healer couldn't heal a group they would be kicked and that is without any quantitative evidence that shows they aren't performing as opposed to other people causing the problem.
If a dps gets kicked because of a DPS meter at least there is evidence to support the reason and not a gut feeling.

Parsers are a great tool for improvement but people are hung up on the one time in a hundred it is going to be used negatively.
If I am playing a DPS class and we are failing because of DPS problem I want to know if I'm the cause.
