ah no wait, actually rare titans do not drop emblems, and it doesn’t really matter for the sake of emblems tracking since loot tiers are common to regular titans and rare titans (rare titans just have a +1 to loot tier calculation)
EDIT: according to this post [KNOWN ISSUE] Incorrect Description of Hero Class Emblems in Version 18 drops of emblems will change, so I’m not even sure it makes sense to track them now
