I don't know if this has been asked before, but during BlizzCon they said "Time travel is always tricky. We're going back in time slightly before Rise of the Horde but once Warlords of Draenor starts, it's like an alternative universe that doesn't affect the present." If that is so and nothing we do back then impacts the future then why should anyone care? I'm not trying to say this is going to be a bad expansion, I'm wicked suped for it. It just seems kind of stupid to have this be in an alternate universe.
