Have you ever played a deep strike in which your transport gets destroyed? You’ll notice that at some points energy management doesn’t cut it for some scenarios.
An issue we find with the missions is that the efective size of a system is bigger than the system for a simulation, with longer travel times, larger distances, and you don’t always get to dock. The solution adopted by the TSN was fuel collectors, although it isn’t the only possibility and other groups chose different options.
Still, it doesn’t come without a penalty. For starters, resupplying means you lose roughly two to three minutes in the middle of combat, so the division has to deal with one ship less. Also, you don’t recover damcons.
Energy management still has a role, because the ship needs to stay up longer, and the work you do is still noticeable for command.
