I'm sorry, perhaps it didn't come out right.
Don't worry about it. I'm drunk and I've been browsing YouTube all day, so I immediately took the part about having nothing to do offline as an insult.
If you can't find something out of all that content that you like to do, then the problem is with you, not the game.
Technically, the problem is with both the game and the player (game can't live up to player's expectations, player's expectations are too high), but I know what you mean and I somewhat agree. If a game is only 10% enjoyable and 90% boring, it's probably time to reconsider paying $15 a month for it - especially when you can play a lot of other games for free.
Like ACL said:
Anyways, I don't think it should be a grind. It's a game, you should enjoy it.
I know that I don't enjoy grinding and I'm not into pet battles, farming, pandas and the Monk class, so I decided not to renew my subscription after checking out the talent revamp. I don't want Blizzard to add more stuff, I acknowledge that I am burned out on a game that I have been playing pretty hardcore for almost ten years. As it turns out, I'm human after all.
