While I do think that the portal semblance is kind of meh for her, I dont think that Raven having a good luck semblance would fit her character. It ould have made more sense for her to have a hereditary semblance like Weiss where both Qrow and Raven would have misfortune semblances.

Also, they're both birds, a crow and a raven which symbolize bad luck as well. I think the portal semblance was just created to be a deus ex machina for when Yang was getting pwned by Neo and needed someone to save her in that moment.
