As the quiet minority here apparently, I don't mind if there's promotion. Sure it will be tough and my players won't get super elite stats, but for some reason that doesn't bother me.
Regardless there's gonna be a ton of re-recruiting once the cap is lifted in the 'A' leagues or if you get promoted to an uncapped league - Your team will not stay the same as it is now if you want to compete in either situation. Even with promotion, the disparity between teams won't be as high as people are worrying about so long as GMs pick up their pouty lower lip do their job.
