If "a harder regular season schedule" was supposed to prepare teams for the WL it didn't work. The same number of teams are promoting and demoting as before. The problem is that the WL still demotes too many teams and the teams that don't get demoted have a huge recruitment advantage (for those teams who still need to recruit).
For the teams that always used to make WL, the structure hasn't made it harder for them to get back in, it has made it easier.
If they only promoted the 8 CC teams the teams that almost made playoffs would get better and the depth of the league would improve. There's no point in recruiting teams to the WL who aren't even good enough to win the CC in their Pro league: they won't have a shot at winning 6 games let alone the 9 it usually takes to make playoffs and not demote.
