Just wondering,
Apart from Admiral Montferrat, is there any reason to spend a nav token to prevent the speed change from a tractor beam at the time it happens, instead of just saving it and using it to accelerate back up when you activate the ship?
I've been running various permutations in my head and it seems like the end result is the same no matter what, just that spending it when the beams trigger telegraphs the intent to your opponent and limits options later when the ship next activates.
Been wondering if I missed something.
