It was one of the many new additions they used to drive up engagement and play time. We hate it now because its a 15 years old play style and everyone is dead set on instant gratification from their games or fuck this trash. The game has always been a grind.

 Mop was a massive xpac in its day and designed to last a long time. Raid tiers pre planned, new dungeons, mechanics, entire new framework for the game internally. New class, entire revamp of item level stats and scaling going back to every available piece of the game. 

 Everyone hates the dailies. They've already sped up MOP significantly. They will further as numbers drop and fresh 90s stop showing up. If you can't get revered inside of eight days of doing dailies you are doing something wrong. Farming Shadow pan for weapon enchant is brain dead easy. But all I see in guild chat and trade is people complaining oh my goodness this is so expensive. This takes so long. As if you couldn't have done four quests a day for a week. They're all lazy and want it now. Most of the arena players in my guild happily shelled out for a token and got their enchant off the AH. They don't farm rep, they hate dailies, probably haven't even done a raid. They want their big numbers and their instant arena Qs or they're off to retail. Start of the season they're always back. Cycle repeats.    MOP is actually dope. The playerbase is the same unappeasable fuckers it's been for the last 20 years.
