So if a dreadnought gives itself wings of Sanguinus, and gets the ability that makes it move like jump infantry, lands in difficult terrain, what happens? Does it test for dangerous terrain? If it does and it roles a 1, what happens? Does it become immobile like a normal vehicle? Or will it take some kind of glancing or penetrating hit? My friends and I discussed this and came to a logical conclusion that since it was moving like jump infantry, it needed to roll a dangerous terrain test because it gave up its "walker" ability. If it fails it becomes immobile like a vehicle that fails its test. I actually called GW on this and they had no clue and said that what my friend and I decided was as good as it could have get at the moment. What do you guys think?
