An English team would want to cop on and win the thing soon, otherwise it just sounds like mouthing. The system is essentially the same one that was in operation when Saints, Tigers and Wasps were winning ***les and yet we heard none of this moaning back then. If I remember correctly in fact it was said that the competitive nature of the Premiership gave English sides an advantage as they were more battle hardened than the CL teams.
The real problem is that Leinster, and Munster before them, have produced outstanding sides that have dominated Europe in a way that has left the French and English sides looking for any reason to say they have an unfair advantage. The truth of the matter is though, that neither the Top 14 nor the Premiership are producing sides of the quality they did 8 years ago. Back then both leagues produced 4 serious ***le challengers ever season. These days France produces 2 and England might have 1 in a good year.
Now don't get me wrong, I do think the qualification system is in need of reform. It isn't fair that the Celtic League sides have essentially automatic qualification spots and can rest players in the league. So yes, there should be a position based qualification system. But would it make a difference to the destination of the Heineken Cup? Probably not. The fact is that our second tier would still certainly be good enough to get us in the top 6 of the CL, regardless of what sides other teams were putting out (and I'm not being arrogant here, it's the truth.)
So in summation, yes, there should be a change to the qualifying procedure, but if French and English sides, the latter in particular, want to be competing regularly for European success then they must get their own houses in order first.
