Hard to say really. I would go for some immortals myself. ABarges are great for their points. As for HQ, I would or actually do take a generic lord to help open a few points. Also depends on what you're playing against. Wraiths over destroyers any day for me. Also would go with bigger warrior units and drop 1 barge, five warriors just really don't put out enough shots, here is where more is better. Of course this comes from my play style. Hope it helps
