So I decided to register my Warhound with the Titan Owners Club. The fact that every titan made by Forge World comes with a numbered certificate proving it is authentic and the production number makes the titan models a little bit more than "juts another model from FW" I believe. The Titan Owners Club aims to get as many of these numbered titans registered with the site for people to see, and by the looks of it, it works pretty well. You can sort by legions to see different takes on the legion colours which is pretty cool.
Hopefully I'll one day be featured on the Reaver as well as the Warlord list. One day. :3
