One thing that I found a bit strange upon hearing about in chat is the fact that inbreeding doesn't have any affects at all in-game. This actually concerned me a little given how (from what I know about Lioden) lots of stat monsters just breed into the pride over and over without consequence. Something that could make people want to buy and trade lions more would be making inbreeding cause mutations. For example, first 3 gens of inbreeding have no effects on the cubs. However, with every gen after there will be a higher chance of getting a mutated lion. Of course, not high enough to make lionesses pop out primals every time, but high enough for 1 lioness to get 0-3 mutes throughout her entire life. But this won't be all sunshine and rainbows, as this will also increase the likelihood of lethal mutations.

This will help newer players in the realm of finding a place in the lion market as they more often then not don't understand breeding items, or can't afford them, but it doesn't hand it to them on a silver plate. However, some people may not like the idea of risking their pride since the more inbreeding there is, the more likely you are to have a cub with a lethal mutation.
Please tell me why you do and don't support!
