First good observations!
Don’t know squat about Dark Souls.
What I do know is this:
BB’s PVE is not that hard in general, but it is intricate for many characters.
GBX put most of it’s effort into the PVP, hoping the PVE would serve as a “tutorial”.
PVE is nothing like PVP in BB so players get familiarized with PVE, switch to PVP and get stomped.
It’s worse with the population low like it is now because pre-mades roam the wastelands looking for PUGs to stomp. When they stomp, new players leave. This is what happened with the Humble bundle. A large influx of players and then a big drop off. Why, no one likes waiting in long lines to get gang-slammed by a group hardcore of veterans.
If you stay in PVE for too long you find that at CL100 you stop gaining much. Once you level 15 your favorite characters there is almost nothing new. No more XP, very little $ and what $ you get doesn’t buy much.
GBX is great at story. They are great at Characters. RPG-FPS and they are in their sweet spot.
Play to your strengths GBX. Beef up the PVE. More story, more levels. You have almost 300,000 owners of this game on PC. Give them a reason to return. No more magic acts, no more Randy Pitchford sing-a-longs.
