I agree with this. The only thing that wouldn't require time is coming out straight away and saying it's all over for the Rebels.
There's been heaps of criticism of how long it has taken for tickets to go on sale and most of that blame seems to have fallen on Rugby Australia. These things are complicated and have lots of parties involved, many of which won't have the issue at the same priority level as it is for the Rebels and Rugby Australia.
You've got Ticketek, MOPA, PwC, some caterer at AAMI Park, lawyers for Rugby Australia etc. who all need to be involved for agreements to take place and for almost all of them, this won't be the biggest issue they're trying to deal with right now.
