It's the same as it's always been.
I honestly don't get the anger towards an offside. It's like moaning about the ball crossing the line for a goal.
You're on or you're off.
Without VAR, you're on or you're off and the linesman would make a decision accordingly, including if he thought your big toe was offside.
There's also never been a 'benefit of the doubt for the attacker' even though it's a myth that's regularly claimed. It's also nothing to do with clear and obvious.
Offsides should be something that many are on board with as it's similar to goalline technology as it's giving us a factual decision, albeit not as quickly. However, hopefully that will be improved next season.
