That's a good point; though I'm less concerned about Electronics and Forging, as they're very much secondary to Education and Psyker in my prefrence, but I'm not opposed to having them be strong/developed.
I think that @King Aurthur is partially right in his assessment below: we need to ensure that our ground-forces are hard-hitting & high-morale... which is why I would like to revisit my Personal Warloard Titan project. (I do have some bonuses in my pocket, and we could dump `Extravagant` and `Rare` quality into this titan to make it really nice.)
The best way to get immediate power-ups is, ironically, to push forward with developing things to boost either our troops or ourselves. As an example, remember our Personal Armor? It's pretty amazing, and we produced upgraded armor for important-people/heroes partially because of what we learned producing it. And we also have our not-quite-Astartes Power Armor for our regular Army.
Remember: ilbgar123 has said (a) that there's a narrative physics in play here, and (b) things run on Rule of Cool -- which is why every faction has giant Mecha and they kick butt. We can use that to our advantage with our personal titan.
