He would lose access to the Black Mace though, so it's a trade off. Honestly I don't even use
DPs in
CSM lists because they are way overpriced for what they do, in my opinion. Everything they can do, you are better served by allying in Chaos Daemons (who can do it cheaper and more effectively). For example, your
DP here costs only a few points less than a Bloodthirster with the D-strength weapon, which I would much rather have than the
DP for the price.
Since you are playing Iron Warriors though, and are sticking to the fluff, I'd say you are definitely just going to have to suffer with some gimped lists.
A few minor suggestions would be to try to cram
MoN on your oblits, to help make it harder to double out their toughness. I'd drop the havoc launchers on the Preds, as it seems like you'd have conflicting target priority with them. Lascannon sponsons with the Autocannon main is more suited to stripping hull points off vehicles, whereas the Havoc is too weak to bother with vehicles, making your targeting priority an issue. I'd rather upgrade the turret on one of them to another
TL Lascannon for the points of those two launchers, and make them even more effective at killing vehicles.
That's just how I would go about it, take it with a grain of salt
