So, say LFR is removed from the game completely. How long would it take for people to hit up the forums, complaining about being FORCED to do Heroic dungeons? Then after Heroic dungeons are removed, how long before people complain about being FORCED to do Normal dungeons, then after all dungeons ever are removed, how long before people complain about being FORCED to do quests for gear?
Do you play any other MMO except WoW? If not I can understand this argument of yours. But personally I play other games in which gearing up has several paths and you can choose which fits your playstyle better. I have come to miss those choices in WoW. This game is very outdated and linear compared. LFR was introduced in the latter parts of DS and as such I don't think you can compare it with something like questing (which has been a core part since day one). It's a new feature which a lot of people don't like, and unlike pet battles it does offer significant upgrades and people do feel forced to go through it in order to progress. In other words: A new feature people hate, but cannot justly ignore.
