In my opinion and a couple of other people I've asked, impression seems a little wasted. I mean, it's useful when you're just starting out and you need to claim some lionesses but after a while, you don't really need to claim any more. And, there's only a couple of things you can do for certain impressions; the raffles {being dreamboat}, claiming lionesses and getting a stat everytime your impression level as a dreamboat gets 100%.
Impression levels is, I think, a good concept and I think definitely has potential but the problem is, it doesn't have much uses.

So, my suggestion is to somehow make some more uses for impression.

Maddi (Side - Fiery Stud) Suggested -

"I always liked the idea for impression lvls to have a chance on finding different base lionesses- not the usual ones we find now. If you are dreamboat. but it'd be very rare to find the base, basically it'd be a NCL only base- not able to be passed down easily either. had like a 10 or 20% chance of it and you'd be 'alerted' of the chance the claimed lioness might be 'different' before you click the link.

Kinda like when it alerts you of a in heat. It'd be more so along the lines of "A strange female is in the distance." or somethin, but this base would be in explore only. Can't be raff And it'd have to have that reeal low percent on reproducing ;3 Or it'd just be.. well not something to work for at all!"

Another by Maddi;

"Plus, I think it'd be nice if we had an NCL to look for, something you can't breed easily. And, is hard to locate also.

It'd give more information to those who are dreamboat, and she'd be hard to impress. Even as a dreamboat, you wouldn't get her automatically like the other's.

It might be like with the raffle girl, you're impressing her, but for a NCL claim. Maybe they can add on a few more buttons when it's a "rare/strange" looking lioness in the distance. Aka, you can try to claim her, if she doesn't look impressed by all the current options. They can possibly add an option to "hunt" for the woman, or show your 'sensitive' side with the cubs in your pride."

Also, other suggestion sort of from Maddi and Axel but maybe special markings or bases for certain impressions?
