Chroma seemed to suggest putting the marines in overwatch instead of breaking the monoliths, thus allowing the monoliths to support in assaults. I think I can live with having one or two necrons dead, some blast markers and -2 from blasts when entering assault if I can potentially get 7 x FF5+ support attacks.
You should really go read his suggestions again. The idea was Scout units on the outside perimeter, with the OW on the inside.
The perimeter formations could have done things like break Monoliths with assaults, exactly as you did, as that is a good tactic. Then, when the Phalanxes assaulted those perimeter formations there would have been no Monolith support, the protected OW would have been able to shoot at the assaulting Phalanxes, killing units and placing BMs before the assault happened.
