But it's the same with loads of teams, nobody does anything when a team moves or goes bust. In football even teams with tiny supports will have a phoenix club set up within weeks of going tits up.
As for Wales, turning up to internationals is one thing. They have only four professional clubs and they're desperately trying to get rid of one of them. I'll await the full scale protests if and when it happens (spoiler: it won't, they'll shrug their shoulders like the Wasps fans did).
