So, I was doing a little thinking and I came up with an idea.
How about instead of NCLs always coming with 1 level and 30 stats, that you can get one with 2 levels and 75 stats?
Of course, the higher the level, the harder it is to get them.
I think this would be a great idea, since people always spend days just to get their lionesses to a certain level or a certain amount of stats, and it takes a while to do that.

Pros -
It would be easier to get higher level lionesses.
It doesn't take as long to get more stats/level up your lionesses.

Cons -
The higher the level, the harder it is to get.
If you find a high level lioness, you still have a chance at her slapping you.
