Nbw lvls

So maybe this could be a thing. Wouldn't it be nice if nbws kept there wild lvls, like I just befriended a lvl 18 wolf but she is now lvl 1. And maybe to counter this make them a little harder to tame.

I think either this or maybe having level 20 NBWs have higher starting stats and level 1 NBWs starting with maybe 180 or 190 stats?
