Note that this is the gameplay frequently encountered in ARMA 3; infantry can get anywhere they want to on foot. They can get there faster in limited-availability vehicles. They can get there fastest by relying on the mass transport option of helicopters.
95% of players prefer to use helicopters because they expedite the movement process.
Applying the ARMA 3 gameplay to Battlescape would see singleships with a maximum warp speed of 1c in interplanetary space. Capital destroyers and cruisers would be slow jumpers at perhaps 3c and 2.5c. Capital carriers would be fast jumpers at perhaps 10c. Corvettes are a bit of a wildcard, but might also be fast jumpers and may be able to carry one or two singleships.
Note that moving 1AU at 10c still takes 50 seconds, so those speeds may be low. A singleship moving solo over that 1AU distance takes over 8 minutes. It's a hike, but it can be done. Sadly, it's much more boring that walking across terrain. But when moving over shorter distances, such as between moons, singleships wouldn't need to wait for the carriers.
One of the really interesting multiplayer aspects of ARMA gameplay is getting transportation sorted out. Carriers have different capacities and speeds. They can also bring in logistical support such as repairs, fuel and ammo. Those are all things that could make Battlescape gameplay more varied.
