While true they've done some map tinkering now, if there is no world revamp then I have to once again ask the question "Why are we looking at a 2023 launch?" If this was an entirely cut and dry (and bad) BFA/SL clone why can't they shit it out by the end of the year?
There's something bigger going on under the surface of this expansion that's pushing back its date far enough that Blizz felt the need to do essentially an extra Season out of the blue.
But yeah that random stable in Stormwind is weird to me, too. One thing I noticed going down the front page is an encrypted mount(?) that uses Harvest Golem sounds. It could be that stable is related to something that's happening in Westfall as the counter-balance to what the Horde's doing in Lordaeron. Then we have everything kinda balanced out, Dark Irons - Blood Elves (heritage weapons), Tirisfall - Westfall (story progression).
