It says on Ventresses wookiepedia page that she was a Sith appretice.
On Savages wookiepedia page it also says that he was a Sith apprentice
Based on that information, it makes zero sense that Ventress doesn't have the Sith tag while Savage does, especially given that the version of Ventress we have is the version prior to Dooku's betrayal.
The only dark side force user in this game currently who shouldn't have the Sith tag is Kylo Ren, simply because he isn't a Sith, he's the master of the Knights of Ren. Besides I'm sure he will get something sooner or later, but Ventress needs the Sith tag.
