Technically though offside is not subject to judgment. When the ball is played a line is set and anyone over that line is off. The linesman is asked to judge that but he is either right or wrong. It isn't like a foul where different people can think different things without it being black and white.
I don't like how it is being used currently but I watch enough sports with replay that I'm not going to sit here and say everything is ruined because we are tightly enforcing offside. Let's maybe tweak things instead of totally scrapping it.
Problem is no other sport is really like football, is it?
If someone is a couple of yards offside and scores and it's given then sure, let VAR intervene.
If someone hand balls it in the build and it's given then sure, let VAR intervene.
Right now it is being used almost constantly and almost exclusively not with regards to clear and obvious errors.
It is not rocket science to see the way it is currently being utilised is not of any benefit to football and it's fans. Get yourself in a stadium and watch it in action and then you'll understand how it is just not working out.
