I still have no idea why Blizzard located the garrisons where they did. They should have made them instanced areas off of a city. They also should have done a much better job on the cities in Draenor.
Well, they took out the capitals of Draenor and funneled everybody into Ashran. And Garrisons were originally supposed to be placeable anywhere. Of course, both cities and everything else were cut down fairly quick.
Also, the game isn't necessarily showing how old it is. Let's be real. They managed to lose 44%(?) of their subs in a span of 8 months since the launch of WoD. Eight whole months. Not during the final patch lull a la SoO 5.4 year long patch. Not from one specific reason or another (blaming the "East" yet again? really?). No, 8 months in the first part of their expansion, 44%. These numbers were last seen during the BWL patch in Vanilla....9 years ago. Insane.
What that says is WoD was, without any doubts the absolute worse xpac they created. You're bound to lose subs when you announce the expansion, along with all these actually interesting plans. Then you take away probably 90% of that by the time the game goes Live. Add salt into the wounds and proclaim a twitter integration patch as a major content patch, a patch thought of in a whopping two days as stated by the devs themselves. Still refuse to listen to any player feedback after everything. They had 10mil subs beginning of the xpac. 1 0 million. And 8 months later only half of that? It's hilarious to watch cause they're so extremely out of touch, much like all the presidential hopefuls. =P
