You don't seem to get it in every thread like this you make, there is no other side of the coin for a lot of people aka the MAJORITY, not everyone can spend lots of time raiding but they still pay the same money and from the financial POV they have far more clout that the Minority of constant raiders simply because there are more of them.
A lot of people cannot do those certain things and you state that those who put the "effort and time" into the game do not get anything unique out of it .... they do get extra BETTER LOOT and BETTER REWARDS ..... I mean comeon think about it.
This smells again of the "ooh I want to be a unique snowflake and screw everyone else" type of attitude. You raid heroics and you have better gear, more achievements, mounts, titles etc all of which unless you raid heroics others cannot get ..... without putting in the same effort as you call it.
The game rewards effort end of story but it does not alienate 80% of its paying customers by making it so they cannot see the entire game in some fashion.
