It isn't, but only because certain players step up and do the jobs. What would Immerseus be like if all the adds hit the boss every time? What would Protectors be like if everyone just attacked a random boss? What would Sha be like if both the tanks got MC'd every pull? What would Galakras be like if no one did towers? I know these seem Strawman, but the only reason LFR succeeds is because a few people end up yelling out instructions prior to or during the run. It should not be their responsibility to have to do that. There should not be an expectation that SOMEONE is in the raid to organize everyone. wow po
