An elitist is someone who is above average but not on the top (but they think they are). To make it worst, they use this to look down on newer less experience players, completely forgetting that they once, had to die to a fight many times to get to where they are at. In addition, in comparison to real pro players who don't act like a douche, they pale in comparison but solely believe due to their distorted vision of him/herself they are on equal standing but ha ha... everyone knows you're not buddy. Btw, not to be mistaken with jealous bunch of people who hype themselves up as super good players but for some reason they always get the boot in pugs cause they're not "pulling their weight" and their friends pat them in the back saying don't worry, it's not you, it's everyone else.
e.g
Example for eltism:
elitist range dps dude: dude man the monk is not doing enough DPS, my elite illegal parser is telling me (blm) i'm doing 260 DPS whereas you're only doing 251 DPS. Please kick him, he is not pulling his weight.
reasonable leader dude: ? what are you on about solshan?, this is our first wipe... and -20 dps isn't a huge issue... nothing that is make or break.
elitist range dps dude: No man, he's melee, he should always be doing more dps than me!!!!
reasonable leader dude: well that depends on the fight... also your dps would be aritificially higher because there were a group of adds you could aoe.
elitist range dps dude: screw this, i'm out, see you noobs.
elitist range dps dude leaves the party
For the bunch of hyped up kids example:
Desperate males: omg lily you're such a good healer!! wowwwwww *knees on all fours and prays*
Everyone else: ???? why do those guys keep saying she is good, she is not pulling her weight... keeps running out of mana and consistently overhealing with medica II for no reason... *examines her gear* wow, she has a lot of piety melds too in her i90 gear... fail...I feel sorry for the other healer..
