"This army, I think Imperials are going to have trouble hurting from range. Especially with the pulse. If they kill you, it'll be the wall of melta transports that does it, and you've got the three Stalkers, the Scarabs, and the Barge Lord as a big "fuck you" for the wall of melta transports as it approaches. Again, I think it's really important that the Scarabs bide their time in cover, getting bolstered by the Spyders, going to ground if necessary, rather than going off half-cocked and getting killed before serving their purpose. I'm nervous (even more so than with the other list) that 4 Troops aren't enough, but, hey, they're Xenos, you gotta think outside the box.

Bad matchups I think are Tau (can you kill everything else before the Broadsides kill you?), any kind of "world of pain in Land Raiders" Imperial build (slow / no countercharge is a problem, even though you'll probably blow up the Land Raiders before they get there), and Dark Eldar (range is too short, Lances hurt, Night Fight doesn't help). "Quality" IG (Vendettas and Manticores) might be a problem, although I think "Quantity" IG (Hydras, Autocannons, and lots of melta in Chimeras) is doable. I think this is actually a pretty decent anti-GKs list, except the Spyders / Scarabs are kind of wasted (since they stop 24" away from you instead of rolling all the way up to melta you)."
