Blimey. Half your points are in you HQ. Thats... a very unusual way of playing. It is a good point that Mephiston might very well destroy everything in such a small game. On the other hand, he may fall to a lucky shot, take out 22.5% of your points, and leave you very short of bodies. You can get 8 veteran marines or 10 regular assault marines for a similar points cost.
I'm not sure I understand your transport options. Which squad takes which? Who doesn't have jump packs? Is your DC 3+1? Are they in the Rhino with Corbulo? If so, why aren't they JP with Lemartes? If they aren't (in the Rhino), why not, and who is?
I'm not sure I'd use the scouts in such a small game (I have some, but I don't use them much TBH). With BA, every point counts at low levels. You have to pay for DC, so it would be stupid not to take them, for instance, but a 4-man unit isn't terribly effective, so adding a few more bodies would be useful I think, and dropping the scouts might be a way to help it to happen.
So, making the DC the main assault unit makes some sense - they are the only assault unit that you have to pay for. You can't get 2 troops without paying for 2 DC. But those troops could be tac squads. So; the only assault unit you don't have a choice about.
Given that fact, it makes sense to make the DC fearsome. Rhinos, I reckon, aren't as good at this as jump packs. I'd say the best place for DC is in the enemy lines, as soon as possible, not standing near a pile of molten slag on the battlefield somewhere. And if you're giving them jump packs, Lemartes is the best choice for someone to lead them, no question.
Otherwise, difficult to comment as I don't actually understand what you're trying to do, sorry.
I love that you're calling your spare DC guy a "Death Companion" though, nice one :thumbsup:
