So we're chasing Garrosh back thru time woopdedoo

So we're chasing Garrosh back thru time woopdedoo, I'm getting tired of saving the world from this orc. Seems like a large patch to me as well instead of a new Xpac. We'll meet some of these great ancient orc leaders & learn of their clans-don't really care about that. Make a Wow Gold garrison-is that due to lack of content in expansion? I enjoy questing & learning lore thru that, so perhaps they'll be enough of that for me. At first glance, seems like a lame xpac.
