A bag of the equivalent amount of Dilithium, the amount depending on the final worth of Dilithium, of course.
Seems only fitting since Dilithium replaced Emblems in the first place. Also, those that already have the Emblems will be getting the equivalent amount of Dilithium, so why not do the same thing for those that will be getting this reward in the future?
I don't want anything, to be honest. I'm pretty happy as is, I don't really need anything. Sure, I wouldn't complain if they threw some Dilithium our way, but if they don't that's cool with me.
That said, there isn't really a way to access the TR-116 right now in any way, if I could have anything I wanted it'd be that. It'd still be relatively rare, though obviously those that already have it wouldn't get anything so might take issue with that. Maybe a token for a choice of 1 from a selection of ground weapons including the TR-116? Not sure how that could work.
