I'm planning to revise space transportation for ground units. Since I've rescaled all units to battalion size (in name, price and build time only, so you'll still be commanding platoon sized units in an actual ground battle), and I'm thinking about rescaling it even more (brigade or even division size) to make the game more realistic in nature (a division capturing a planet is more close to sane logic, than a platoon), and unit costs and build times comparable to space units. Since these are way larger units (battalion around 600 troops, brigade around 2400 troops, and division around 10000 troops), they will not travel in stormtrooper or galofree transports obviously.
What do you think transportation in space should be represented?
Link land units to capital ships? Like the hero units, they would be carried on board of a capital sized ship in case of a space battle. This would mean however, that they'd be really vulnerable since all ground units in the fleet would travel in a single ship. Plus it's pretty stupid to think you can carry say 5 infantry divisions on a single ship.
Should they get their own transport ships (like stormtrooper transports are now, but in capital size)? If so what starships you recommend to be used as dedicated ground unit transport ships in space? Remember their main purpose is not combat, so I'm not thinking of ISDs. Acclamator I is a good example of a troop ship, so think along those lines.
Problem with this solution is the need for a shipyard in orbit to actually produce the transport ship, and the extensive cost of the ship+ground unit, which makes building ground units way more hard and costly.
