To be fair if you are a returning student you would have missed out on way more time, just saying. I think I would have missed out on almost 6 months of university, not counting the multiple weeks of disruption due to strikes (which isn't related i know)
While I'm not one of the people who want to defer, I understand why, because online is not the same as face to face, and next year will be a sad year really. I am sad since I won't be able to hang out with my society, to actually have a good social life, i definitely won't be able to come back to my work (i work at a school part time) and so on. If people are paying for something, they want to get the full experience of it.
Besides, when you defer, the logic is that you have a secured place, you are just taking a year out, so you arent risking your place.
