The only possibly legitimate argument for the Champ becoming harder next year is that FFP relaxation will mean more teams can legally chuck a bit more cash at a promotion punt. But even that doesn't make it 'harder', as a) everyone is in the same boat (cash notwithstanding) and b) it lessens the impact of parachute payments. So I'd say that is spurious as well.
The only real measures of how hard a league is are the number of points required to either get 2nd or make the playoffs and I haven't seen any trends to support this, though happy to be stat****ed.
Thumbs up purely for the phenomenal use of the phrase "stat****ed".
