Accustomed benign unusually short

I have played both parts of Borderlands intense alone Part 2 over 400 hours, with some DLC's course.
All the more disappointed I was when I in less than 20 hours of play the guy I had barely made sah.Ok side missions, because I wanted to save it for higher levels of difficulty to still a few surprises.
The Pre-Sequel is certainly not a bad game. It makes a lot of fun, like its two predecessors just as well.
But it is now times much too short for my taste. When DLC for me from 20 euros it would have been absolutely amazing.
But for a full-price titles (especially branded Borderlands) I expect more content.
