I'm starting to get really confused with the storyline. Aetheric disturbance this, soul vessel that. There were lots of lore-based science that came out of nowhere and I had to take those at face value. I enjoyed main ShB story, but so far post ShB has been like... "mmk, whatever you say, fam."

Then again, please try to be fair when comparing the expansions. You listed full 3 & 4 features combined vs. 5.25 (approx. 50% of ShB). ShB doesn't and won't have equivalent features, but it brings new ones to the table as well. Let's try to look it objectively because when SB was recent, there were lots of complaints too.
