I suppose that's one I can't answer as given the opportunity we would look to go through this process. It seems that all manner of titles are routinely offered up to suit so there is no change there.

There is still a place for 5 nations when delivered in context.
'Context' for me would be (for instance), any National title holder. I would also accept an area title holder if none of the above are available, but look to involve the other champs in the mix moving forwards. This in turn would result in vacated titles for up and coming contests. It also means that the level remains at domestic or just above - rather than a mass of less qualified fighters going to European because that's the only option.
