I've taken liking into Trial of Valor mythic transmog, however I hear from some sources only way to get shoulder and helmet appearance is through chosen achievement, which is gone, and from some I hear it can still drop on Helya Mythic.
Anyone that can confirm either claim?
Its gone removed in pre patch to BFA.

Chosen transmog sets are removed in BfA prepatch and can no longer drop. Shoulders and helm for all 4 armor types aren't accessible anymore, but rest of the parts share their appearances with mythic ToV drops. So if you are interested in those you can farm mythic ToV.
