Two points
1 I believe that now is the wrong time to make any decision other than to further investigate the faults before making a final decision on its use next season. The biggest being the actual decision making I believe that should be left entirely to the VAR,
2. FIFA being the governing body can make whatever decision they deem to be in the interest of the game so I think they could insist that its use is continued in whatever matches they decide.
I must admit to taking the statement about them voting against its use next season at face value without reading the in depth report.
One point. It is shit and nobody wants it (other than you it seems).
