There’s absolutely no substitute for watching live football and especially in the the lower leagues, where income from match days is paramount for survival, I think It would affect attendances big time and I’m talking about the casual home supporters more than the loyal away fans.
I think the majority of away fans go for the experience and the day out so I don’t think it would affect travelling support too much, except for maybe the long trips to the other end of the country.🤷‍♂️
It’s great for people who’ve moved away to other countries to be able to still watch their hometown club but other than I wouldn’t change it.
