Tiggy rolls on biomancy or divination depending on how badly I need the cents to ignore cover. Centurions and devastators hang out with the techmarines in 3+ ruins. Depending on the army I'm against I will probably drop both ironclads turn 1. If I really need the grav weapons and I roll endurance with tiggy then maybe I'll drop the grav squad on the first turn. (just realized while typing this how awesome endurance would be on that grav unit. 25 shots, almost half of them grav and the rest bolters with combat doctrines will devastate any infantry unit I can think of
