A lot of us like her because she is a fire cracker in and outside of the cage.
She has a potty mouth, and can get some good pre fight hype going that gets the fans stirred up to either really want to see her beat up someone or to see her get killed. Ronda has a similar effect on people, but Juliana is a lot less known. But for people who do know a lot about Juliana, THEY KNOW. Lol!
I get that she hasn't fought that much, but that is mainly due to injuries. Every time she steps in she mauls people though, and beating the crap out of her last opponent (why can't I think if her name) was a great win. That was going to be a tough fight for both, and Juliana took it to her pretty easily which proved a lot. She isn't intimidated by Ronda at all like so many other opponents of Ronda and and we know that she'll scrap like hell when she gets in there.
Unless you just don't like her mouth, then I don't understand what is not to like? You don't think she fights with an exciting style?
