didn’t see that the expansion would be included so… i didn’t bother. i also thought that part was obvious? IF the expansion was included in that version they would CLEARLY state so. sorry to say this, but that’s on you buddy (they ALWAYS tell you what you’re buying… great lesson you didn’t realy need tbh)
also, without the expansion you’re locked out of the new zone and some new end game content (wich is located in the expansion zone) and you’re just able to play everything you could before.
