Talking about the class hall in this case. It takes roughly a month of real time regardless of how much you play the game to fully upgrade your class hall and I kind of wonder why..
The requirements are already fairly step from a resource perspective adding two weeks to complete the last step of it seems overkill. I don't really see the purpose of it. If it is to act as a nerf it seems bizarre since it is going to be available roughly around the second week of mythic.
I don't know is there something I am missing? Making things take a long time to upgrade and tying large amounts of player power to that just seems like a kick to the nuts for alts.
