I think the only downside with pushing Nattie is that it's basically filler. We're probably past the point where Nattie can really be elevated to being a top star. She doesn't quite have the potential ceiling a Bianca or a Ruby or a Sonya might. But if she's put in any position, we know she can reliably get the job done. She's a good dependable place holder.
Not trying to be mean... I like Nattie. She's always solid. Just not something to be excited about.
