Not that I see why that matters, as if Swtore would know secrets about Vitiate yet mess up the basics of how being a Sith works. I'm pretty the rest of the game also refers to you as the Inquisitor in the loading screens, other parts of the codex and such too.Apparently not the case. Too bad.
I love that you’re currently putting this much faith into the title of ‘The Sith Inquisitor’ as if the quote doesn’t state ‘an Inquisitor’. The actual quote discusses the blades an Inquisitor ‘often uses’ and general skillsets. It is evidently referring to the rank, and not Nox.
Furthermore, as I already stated, Nox would continue to train as an Inquisitor, yes, but the quote wouldn’t apply to training outside of that Sith rank. Inquisitors generally are as good with a blade, but one who specialises and excels in the force wouldn’t automatically keep as linearly proficient with a blade, as said specialisation would not be as ‘an inquisitor’.
And for the record, literally every (canon to the story) advanced class mission makes it clear that no Sith specialises in both. Jack of all trades, master of none and all that.
