I know everyone despises the bog roll tickets, but having used machines with the standard square tickets which had a tendency to jam, spit out smudged or blank tickets, etc they seem like a welcome alternative.
As for mandatory reservations - I'm really not sure I understand the gripes. You can make one up to 5 mins before the train leaves, you just have to type a few details in the LNER website, and will spit one out if your ticket doesn't have one. It's really not the biggest nuisance in the world (compared to wearing a mask for hours at a time on board)
