True, and it's probably unfair to entirely discount that, but considering this is specifically marketed as an expansion and considering the weight that has held in the past, I still feel like it's not unreasonable to have expected more than something that's just about equivalent to interim content drops.
I also realise there's a lot of work that went into overhauling the gearing system etc., which seems to be very much the focus of this expansion, but that is exactly my issue with it. To me, the story content feels tacked on alongside what they really wanted to push out, a systems update.
