honestly I've never seen that unit used before or mentioned and I'm going through a lot of serious builds at the moment. seems decent though. Only thing is from what I'm seeing there's no inv. save so plasma death on them will win, or any ap 2 weapon basically.
but on about Deathstars I suppose. I never really had any problems with deathstars as try and have a load of my units buffed enough to take them out with relative ease. For example I have an honour guard unit with blood champ, chapter banner, power weapon, flamer and a fist, totalling 260pts. Went up against 7 thunder hammer storm shield terminators- 280pts I think it was? Anyway by the time they got to strike back only one guy was standing and he only took out one guy. my other assault squds do better than that often enough too. I'm sure roughly the same tactic would apply to that unit.
