I kinda don't get what you were aiming here at but let's assume...
So you want to say clearing the hardest content doesn't mean anything in game? As someone who is doing that all the time since Vanilla, I can tell, it's get more aprreciation in game nowadays than it used to get in Vanilla and TBC. At least I'm getting much more whispers about the gear I have or how well my performance is if I happen to pug something. In Vanilla and TBC there was far too much unhealty competition between people and completly pointless elitism that made it impossible for people to actually enjoy someone else's acomplishements. The funny part was that it's always the casuals and bad players that acted in the most elitist way back then :> Because they thought that having access to "exlusive" content makes them somehow special. Shame, skill wasn't needed for that...
