Yes any DPS Parser can be used for elitism purposes. However a large amount of people use it for good purposes. For example, one of our raid groups was doing ADS2 last night, the group was a little melee heavy so normally they would clear left then boss. However the group was used to the mechanics of going right and doing the boss. So one of the members using the parser evaluated DPS on the boss to determine what kind of physical DPS loss they were looking at and if it was possible to even do the right side. When all was said and done going to the right side did affect physical damage but not as much as they had thought and they were still able to do the boss once the numbers were plugged in to the time they had, with time to spare I might add.

I know a large amount of people use parsers for personal improvement which is what they are meant for. Parser or no parser, those elitists will always be who they are and there is nothing you can do to change that. Even without a parser they will still boast about how they can pull threat or how they are the best or whatever the case may be.

Example: Running CM and the other tank who has less hp has one of those Elitists attitudes, did not like how I tanked things and he just tried to wipe us during the rest of the run because "hes the best" and "he knows everything and you have to listen to him". Dude talked down to everyone in the entire group and I ended up solo tanking, which is fine, no problem.
