At 1850, I run a grandmaster with mastercrafted weapon, icon of the just, pyscannon, and hammerhand (for dreadnoughts). I might think of dropping 1 Terminator squad for something that can go toe to toe with another beefy HQ. I have killed a marine captain more times than I can count with his force weapon. Also, I think automatically deepstriking the terminators can be a mistake. You split the chances of a bad role meaning they don't come in until everything else is dead, but if you are running 2 LR they can just run behind them. Each terminator squad needs 1 thunderhammer, otherwise they could spend the game stuck attacking a dreadnaught. Since the whole list is punch you in the face I would go with a MM/DCCW dread and have it advance with the LR. It can tie up an infantry squad if they don't have a fist.
