The volume of linesman error Vs var error isn't even comparable. Having the var tech has undoubtedly improved the accuracy of games, but the application is overzealous and the administration beyond words.
I think after this season we might see a consensus to strip it back. Maybe to goal line tech, onside - on/off (IE like the linesman flag).
Maybe, and it's a big maybe, add to that - the ref being able to ask var to help (like rugby) and maybe each team having, say two var appeals per game (becomes active an next stop in play. Agreed that if accurate, the subsequent play is treated as having not happened. That in itself has issues, like injuries etc, so may not be practicable).
Going to no VAR would just put us back to a huge officiating controversy every week or two and the association furore. Let's forget how ridiculous that was. The game is well passed being able to be adequately officiated by one ref and two linesmen.
