So the current design of blackholes is.. Well suck you into them and, well.. That's it, I saved before going in and needless to say I got dissapointed lol
And stars need to be scorching hot against armor and hulls because if something has a 15 million degree scraping against metal, you best believe it will melt waaay before contact lol, maybe to counter that a certain ship can have a special mod that allows the fleet to approach with less % damage, stackable effect even
As for blackholes I think that when a player gets closer to them, CR degradation should increase exponentially because well... Time and space! And speaking of time, it would be more challenging/realistic if In-game time starts to rapidly increase or even skip days the closer a player gets to a blackhole
