I'm not sure that what you wrote there contradicts what you said I was saying.No you don't, you're self-admittedly campaigning that "the game should be extremely easy, to the point that my hamster could succeed at it". I'll talk from the viewpoint of shareholders, try to refute.
The shareholders want to maximize income, specifically subscription income since everyone buys the x-pack anyway even if they quit soon. To maximize subscription income devs need to incentivize non-raiders to play the game and stay subbed all the time; raiders will stay subbed for raids anyway. To incentivize non-raiders to play the game the devs need to make solo / small group content rewarding, more rewarding than LFR to make sure that non-raiders stay subbed after they inevitably clear LFR on the first day it becomes available. Ergo, dungeons / world content should reward higher ilvl gear than LFR, making non-raiders increase shareholders' income.
