As an outsider looking in that doesn't play WoW or it's many, MANY expansions... (My girlfriend does play it/them), I can see how even with new content, the arbitrary extra 10 levels (level maxing) and dungeons+bosses get repetitive and monotonous, including the "dailies" you have to do, just to keep you on that monthly/annually subscription hook... And it's not really the dev's fault entirely, it's just how that genre is... Blizzard not only cornered a market, but they also accidentally backed themselves into a corner in the process.
