Okay, so I'm throwing this out there because I think I may not be the only one feeling this way. You have the right express your dislike for this idea, but please be respectful if you do so and say exactly why you do not like it. :)

Superior Aging Stone:
Ages your lioness/lion to 2 years of age. Automatic breeding cool down placed on lionesses at use.

Cost: 4-5 GB (since the regular aging stone is 2 GB)

Reasons:
I really don't like the idea that my adols and cubs are pretty much useless to me right now. I know I could age them to adols and cut back on their grow up time as cubs, but I can't do anything with them really, so I have no reason to buy the aging stone. Some love it, I know, and if you don't mind waiting that long for them to grow up, that's great.

However, I would like the option to skip the adol stage all together and get to training my lionesses faster. This would allow that to happen, but it would also prevent you from automatically being able to breed her right off that bat. She would have an automatic 20 day cool down placed on her once you use the stone. Males can use it too but there is no real need for a cool down as you can replace your male early already if you pay the retire early fee.

I think this would be fair considering it would give you the opportunity to train earlier so you can actually do something with those cubs or adols you have.

Keep in mind there is a post about allowing adols to train being shown support in this category. l support that as well, but I think this would be a nice option to have if you just want to skip the adol stage completely, as I do for certain cubs.

If anyone has any tweaks that could make this better (not making something like this for SB, sorry but it's too much of a boost to be an SB item), please feel free to post them. :)
