The extra time we get now is just one step away from ushering in a game clock.
We effectively have it already (hence the increase in added time) and it's killing a lot of the time-wasting >>> Good thing.
Regardless; making an announcement will take no further time.
A lot of decisions will always be subjective , but at least pre-var we knew the ref just called it as they saw it , and mistakes were more understandable and forgiveae.
They weren't being forgiven/forgivable(?) any more than they are now.
Bad, costly decisions don't get forgiven or forgotten.......
