True but they were a lot of fun to find, and then defeat. Clearly when added there would be A. Update mention them and that you have to find them. B. Mention of them in the DLC and that you need to find them. Adding an Achievement or two for hunting them and killing them would also get people to search them out, also adding Grimoire cards for them. SWTOR didnt make them very well known, they were kind of like a big destructive easter egg.
