I dont dislike the current structure personally. There are numerous benefits;
- encouraging teams in the championship to spend money as more than one team can be promoted.
- promoted teams need to be of higher quality in the middle 8's than those they replace
- gives importance to the championship games and a purpose to play for
However it is a rather complicated system and explaining this to non RL followers is a difficult task and leaves them confused. This makes gaining new rugby league followers more difficult, and it's hard enough anyway for some reason.
I think it would be better to have a system similar to scottish football. Set leagues of 10-12 teams. Bottom team is relegated, with the winner of the league below promoted. The second bottom team from league 1 joins the play offs with teams 2,3,4 from league 2 to get promoted back to their league. Then just leave it at that.
The issue with the RFL is changing things for the sake of it. Dont fix something that's not broken. What was wrong with how it was years ago with straight promotion/ relagation?
