It may just be the player. I personally complain about everything I see going wrong in a dungeon, only if it's THAT wrong. I won't complain in party chat, since I don't like to be rude, but you see things man...as a BRD I see DPS not using DoTs or staying in AoEs, as a WHM I see DPS not buffing themselves with their self buffs or moves that do it (like Heavy Thrust), as a GLA I see people doing stupid positioning and often attacking before I Flash or even get the first hit in. Actually, if you start doing ONLY Duty Finder or Duty Roulette to level a class, you start seeing horrible horrible things that make you facepalm and rage, usually to the point where you give out 0 commendations because nobody has really earned it.
