The leagues were a good idea, as before rugby was entrenched in certain clubs that had agreements to play each other rather than being more meritocratic. Unfortunately the way that the leagues at the top have been structured, even more than in football, have solidified an elite set of professional clubs and prevented other clubs from having a look in, so after a few years of real gains for English club rugby, it feels like the trap door has been effectively sealed shut for the Premiership cartel again.
I think the standard of rugby in the premiership has improved though I agree.
