I think the argument is that people playing the gold league are gaining an unfair advantage via training and morale during the close of season. Also, if you're savvy you can dodge paying for friendlies, and still get full benefits.
The only obvious solution is to scrap it and any other leagues where you gain an advantage
Unearned benefits (other than signing up for a PL) should be available to all - or none? But some extra benefits can be earned. Qualify for any evening cup and there are immediate benefits when cup rounds are played over those that don't qualify (and the more rounds passed through, the greater the benefit over a season). Which is, IMO, fine, But scrapping the Gold League and any other leagues where an "unearned" advantage can be gained surely doesn't have to happen. Keep any unfairly beneficial competition (with the history) but remove the extra training benefits.
And BTW, Is it me or am I imagining a (slightly petulant) resistance from some to the idea of bringing the Gold League in line with other PLs?
If there are to be some leagues with bonuses, maybe there could be one for females and one for males? Existing managers only. Loads of blokes competing for places in their league and (as far as I know) only three of us gals taking up spaces in the other league (apologies to any other female managers that are out there. How about making yourselves known?).
Or just scrap all training benefits from daytime competitions (except Friendlies) and make sure all daytime PLs get gelling benefits for the players that take part. Is my opinion.
