I'd rather not have VAR at all in the current format - it's removing the accountability of the decision from the ref and this leads to lower quality decision making in the long run.
Rugby uses the TMO to show why an on field decision shouldn't stand if the ref has doubts and to highlight impacting events that the ref didn't see in the build up to an event like a goal. At the moment VAR is the final word so refs aren't "responsible" for the answer in the big decisions.
"I'm giving the goal unless there is an immediate and obvious reason why not" is different to "You need to overturn your decision because under several minutes of stop motion scrutiny we saw the defenders left thumbnail was fouled by the attackers right armpit"
