VAR is good for correcting obvious mistakes, remember forest losing points due to a handball goal near end of last season - no VAR in championship, luckily it didnt effect promotion relegation. Then watching the 2nd Division playoff final won by penalty that was'nt a foul & wasnt inside the box, a decisive goal that could've been ruled out if there was VAR.
For offsides the moment they freeze the frame & draw the lines are marginal, i'd like to see rule if the lines are close enough to touch the attacking side gets the advantage.
