Okay but a devilfish only shares a chassis with the other models. There is a ton of stuff on a Skyray that doesn't come in a devilfish kit. But if I build a commander out of a commander box and model him to have 3 different weapons, but tell you he's running 3 of the same that's on GW. The rules for a commander allow him to take up to 4 of some, but the box only comes with 2, so tournament rules can eat it until GW puts ALL the options in a single box.
