Now I know Sub-male Breeding is a horse that has been beaten to death. But Other then patrolling them boys do jack squat to contribute to the pride and their extra slots are EXPENSIVE. So an idea that would give value to getting more then the base 2 slots for 500Sb would be to introduce Sub-male Breeding.
However we can't just have them Willynilly running around and knocking up our Lionesses! There needs to be a few contingencys to this.

Features and Restrictions:
Breed a Lioness in your Pride! Fertility still applies and either
a) They have their own "fertility"
or b) They have their own "energy bar" that only appears when they are able to breed.

A cooldown, 20 days like lionesses for the Submale. This addresses the concerns for stud market going down. You'll still need studs, but at least while you're off exploring you do't expect your boys to just sit there do you?
No Public Submale breeding. Only in pride. Again to Address the stud concerns.

Downsides to be adressed:
Cub Market.
Studding Market.
Solutions:
Cub Market: Some users say it would effect the cub market negatively but as we can all tell it isn't the greatest right now anyhow. If anything it would improve cub prices ESPECIALLY for males who aren't quite heir worthy but have a few redeemable marks or if you wanna keep your current kings looks but have a boy you really like or a base you're seeking despite only being allowed two kings who both have bases you also like.
Studding market: I believe that not having public breeding and the cooldown will still have a need for studs. The cooldown will make it so you can't breed him like you would your king, so even if you have a sub with say an orchid base and you're trying to breed 3 orchid lionesses. You'd still need to find a stud to mate the other two. I believe the pride only breeding portion is self explanatory.

Why should the staff do it?
It gives an extra reason to keep the boys around and be choicyer about it, and makes the 2Gb for an extra male slot a little more worth it. It would also be a relief for Clean line breeders due to being able to bring in more clean blood during May.

I know this is a controversial topic, but i'd like to hear your opinions and Ideas and I am open to CONTRUCTIVE criticism. Remember You're not forced to use a lot of this sites certain features and thank you for reading my proposition.

User Input:
Starfruit- What about traditional breeding? A player could easily send someone their lioness to knock em up then send them back with the submale’s cubs.
I say, the lionesses have to be on your account for more than a set period (let’s say 10 days) till they can breed to your submale, unless you BOUGHT them through a public trade in TC ^^

Maybe make a role for submales like the Broodmothers! There can only be one “breeder” per ten territory, and they would have breeder cooldowns (similar to Broodmother cooldowns) and you cannot place another submale as breeder on the day that you took your recent breeder off, to stop people from loopholing?

zizi- maybe to restrict the subs they could have only 5-10 breeding slots per week and use your energy to make it simpler.
