However, commonly the word ''decimated'' is used when talking about ''destroying or killing a large proportion of something''. According to the Oxford Dictionary, though some may contest it, it has now become part of the standard English.
Just saying, it is now the commonly assumed meaning of this term that has superseded it's historical meaning. Whether it's correct or not is a matter of opinion, but the fact is it can be used as either.
In short it doesn't really matter.
And I have no idea what happened in the 5th paragraph but it doesn't seem to sit right.
Anyways, back to the topic at hand:
Every form of attack in Starmade can be countered in on way or another, it seems odd that sun damage isn't one of them. It could easily be weaponized and/or used to the advantage of people either seeking a convenient hiding spot if there was a way to counter it. Perhaps heatsink and cooling modules could be created to help combat sun damage?
