I see your point, honestly it should be IMO given as a regular title then. Here is a list of the current class titles in game. Notice that each class has a title to set them apart from every other class, except the Sith Warrior.

TBH each class has their own specific titles, yet the Sith share Acolyte, Apprentice, Lord, and Darth, as the Jedi share Padawan and Master (as it should be). The upset here is that Inquisitors also have "the Forcewalker" title, Consulars the "Barsen'thor" title, and Knights the "Hero of Tython" title, while warriors are left with just the 4 shared class specific titles.
Being the Emperor's Wrath gave me goosebumps when I reached chapter 3, but my Warrior does not currently in game have a title to differentiate the Sith Warrior class from a Sith Inquisitor.
