We've gone from fixed desks and floors divided by department to stupid flex desks where you have to drag your stuff from a locker and are sitting mixed with people you have nothing to do with whatsoever. Often noisy sales people besides ones that need to concentrate.
I used to enjoy going to the office 3 times a week. Now I officially should go 2 days but I hate it so much I rarely actually do. It's really a fancy place for management to see butts in the seats and the needs of the employees are a total afterthought.
