For me yeah.. the grind is just too much. Grind doesn't interest me, doing the same thing every day isn't what I call progression, I call it being stuck.
The paced is slowed down, so it is either get used to it or leave.
For me it is hard to get used to a slower pace; I don't want to walk back, I want to go forward. With MoP I'm feeling some things are reverted to how it was previously.
