No Sith tag for Asajj Ventress?

Assaj Ventress:

The Rule of 2 in the Sith Order only applies to Sith Lords - the Master and the Apprentice. However The Apprentice Sith Lord, is known to take on a disciple of their own to train in the ways of the Sith and Darkside, so that together they can over throw the Sith Master - starting the cycle of Rule of 2 all over again.

Vader did this with Starkiller (although no longer considered cannon) but also attempted to do this with Luke in TESB. The Sith Master: Palpatine or Sidious instructed Vader to deal with Starkiller and had no knowledge of Vader attempting to recruit Luke.

Dooku or Tyranus also did so with Ventress and then again with Savage. The Master: Palpatine or Sidious was aware of Ventress and she was growing powerful enough to pose a threat to his rule, when teamed with Dooku, so Sidious ordered Dooku to eliminate her. This is why Dooku kept Savage as his new apprentice a secret from Sidious.

Ventress and Savage held the same rank and purpose with Dooku, yet Savage has been given a Sith tag in the game. Savage was also Sith under Maul's teachings - however, due to the Rule of 2, Savage only would have been awarded the title of Darth and Sith Apprentice, once he and Maul defeated the existing reigning 2 Sith Lords - Dooku & Palpatine. So he was no more Sith than Ventress.

Ventress was an aspiring Sith Lord under the teaching of the Sith Lord, Darth Tyranus aka Count Dooku. Dooku himself refers to her as his apprentice on more than one occasion throughout the Clone Wars animated series (which is considered cannon) - and does so in the very first episode when speaking to the Toydarian King:

Dooku: "Yoda's powers have been greatly exaggerated."

King Katuunko: "That remains to be seen Count."

Dooku: "Indeed But when you decide to join us, my apprentice (Ventress) will contact me."

So I ask why a legitimate sith apprentice, fails to receive a Sith Tag - when a non-force sensitive Sith Trooper in the game has a sith tag?
