complete stop (from ftl jump, running into rock, etc) is almost always objectively bad
i think it is room for interesting play though, especially if the benefits pay off quickly and then it is not incentivized so it's not just a "sit still 20 minutes and wait for rod" thing
so: increase passive dissapation to 10x or so when stationary and very quickly lose the buff until ~5 speed (magic thrust speed) - hopefully it loses heat quickly enough that people don't stay in it too long
will also not be too strong defensively since shields are either on the inside or should generate unbearable heat relatively quickly if trying to passively dissapate
this also should make station cheese harder, but it might be silly with the sun
