Space Marines have now become much more shooty oriented to me. Especially with the normal SM loosing their CCW and just having a Pistol and Bolter. I personally believe that Sternguards are much better than the Vanguards for supporting the SMs. There are only a select few that can efficiently CC besides HQ, mostly within the Elites and Fast Attack. They are Assault Squads, Vanguards, and Terminators. There is nothing else beyond those 3 units. Terminators even got the new upgraded Cyclone Missiles, so now there might even be less CC Terminators to sport those cyclones.
