This is definitely a better xpac than either MoPs or WoD was. I would call it a good time to get back in the game. It's fun, lore heavy if you like that kinda thing, and classes have been simplified a bit compared to what they've been lately. It also doesn't really matter what server you're on anymore either. Everybody can do anything with anyone. You just have to have someone from another server on your friend list to invite them.
