Anyway, it was a fun day and I think I did alright given my limited tournament experience. I think I can improve my list. As I mentioned in the reports, I need some more survivable scoring presence. I also realized that I'm very vulnerable to night fight, but I can't think of anyway to fix that without adding vehicles. I'd rather keep my all infantry approach, as my first two opponents both remarked on how they weren't using all their anti-tank weapons to full effect (my last opponent didn't care because Obliterators can take out anything).
I'm thinking that some Scouts would be a cheap way to get survivable scoring into the list, but a Tactical squad would also be a more expensive possibility. As for night fight, I think I just need to suck it up and move in fast against Necrons.
Anyone have any ideas? You've seen the games, and I'd appreciate some feedback.
