You can tell who the LFG/Normal raiders are with comments like this. Even taking a step back from "WoW is a game herp derp", why would someone NOT want to do something as optimal (see: efficient) as possible? For 98% of the players out there the time figuring out the optimal setup is done for you. It's just a matter of copying the spec/gear.
I never understood people wanting to be a part of a team but still wanted to use the excuse "I pay for the game just like you do, don't tell me how to play". No, you pay for the game just like we do, but don't join a team just to drag them down with your disregard for the team.
