Wreth has a resource advantage because they equip their marines with cheap wooden crossbows. That allows them to equip more marines and use their ore elsewhere.
They are holding TC with anywhere up to 4 cannons and 7 squads in defensive positions. When we held TC we had barely more than 1 squad BTW. There is no way in hell we are making a successful landing with just 1 transport. Our mobile covers and grenades would be a solid counter to their cannons if our marines weren't hopelessly outnumbered. Maybe if we get a tactic to secretly reinforce behind enemy lines and tactics for either vertical mobility or proper mobile cover use we would stand a chance.
Our next transport will for certain have a topaz core, and maybe topaz trims. It will be twice as shielded and maybe twice as agile as our previous transports. That's a big upgrade. Still vulnerable to focused fire and incredibly vulnerable to flaming spitballs.
You know what might not be a bad idea? A cheap escort viper. No guns, ordinary trim crystals, no armour, just shroud. It would cost 27 crystal, 7 ore, 12 wood, and 12 silk. Main attraction is the low ore cost. Basically an ablative shield ship for meatshielding. Might even be able to transport a bit itself with the empty gun decks and empty bunks. We would need to invest more in hanging gardens for this to really be a viable concept with that crystal cost though.
We can take Burned Mountain pretty easily, and as long as they don't control both the unfinished and TC we will get the ore. Maybe we can also take Wrackspire at the same time. We can use that extra ore to snowball and take TC. I admit it is high risk because if they gain aerial control of TC they get the TC resources, and if they get control of both TC and Unfinished we lose Burned Mountain.
Ore seems to be the one resource that isn't easy to expand production of; we can't grow it like crystal wood or silk. Maybe more efficient mining or smelting techniques would work. Or we could finish the Mist Dissipator special project and use that to set up less suicidal surface mining operations, or less suicidal surface caravans to the belt spires.
We should definitely invest in designs and revisions that make better use of wood and silk and stop designing anything that uses more ore. Ironwood 2 is by far the best choice because it is still just as important as last time and we have a more experience now so it will be easier and better than last time. We should call it Bronzewood because bronze is actually usable in most situations unlike iron. Then we revise a witch-hunter variant with bronzewood arms but let the design team lacquer it and carve it and make it fancier so they don't throw a fit. We should also try again at leather armour either as a revision or very small design.
Sorry for rambling.
