Alani became available yesterday for the select few who have already invested in Battleborn past the base game. Everybody else will have to wait until May 31 for her to unlock (and then will have to spend a pretty sizable chunk of in-game money to use her).
I took her for a spin through a couple of story missions and competitive multiplayer. She's not quite as easy to use as her fellow Eldrid support character Miko, but she fills some niches the mushroom doesn't.
