In gauntlet the routinely have talisman sets on their toons that we cant apply due to color restrictions. That is tough enough to plan and fight against, but they sometimes have more talisman sets on their toons. It sometimes may be from cosmics talisman that we have not seen yet.

In one instance I went against a gunner dog that had primordials and another set of talisman that could have fit due to color restriction. Either they had a primordial cosmic or something was definetly wrong. There has been many instances of these problems documented by other players. You can complain, but just get used to it unless they fix the problem.
