Source: STAR WARS: The Old Republic - Relics removed from cartel packs.
Apparently these relics were procing but no apparition was appearing. It appears that they are removing them from the Cartel packs so they can go forward with releasing F2P and fix these as they can.FROM Nathan Emmott
I just wanted to pop in and confirm for you all that, sadly, we did have to remove the relic apparition items from the Cartel Packs. We're bummed about the change as well (because we are super-excited about these relics) but sometimes we have to make frustrating decisions like this. In the end, the current state of the relics was not something we were happy with releasing at this time - but! - that is not to say this is the last you will see of them. We will be bringing these items back in a future update!
Thanks everyone for the feedback!
