I think that the original idea was good. It prevents people from mining overnight and others getting pissed cuz the rock is too darn hot to mine anything. A system to prevent overkill afk mining is needed, folks!

Uh, no, it isn't. The ability to engage in scorched earth tactics is important and will become much, much more so once crafting and the economy are fully implemented.

I wonder when this will be...

I agree with the base concept here, that over-heated roids (whatever "over-heated" really means) should do "something" other than sit there and continue taking more heat. Chemical changes such as making lower and lower value materials come out from use of the mining beam. Explosive decompression from gas pockets being formed of lighter elements in the roid. Breaking up of the roid (though I can see problems with this from the development point of view since roids are currently considered permanent structures). Heat releasing other radiation from the roid that damages the ship over time and any other ship that gets too close.

Lots of idea, but something should be implemented simply because it makes no sense that the roids can get so hot, such as thousands of degrees K, without anything else happening to them other than heating up.

"Heat releasing other radiation from the roid that damages the ship over time and any other ship that gets too close."

To this idea I say yes.

Well thank you. That is the main purpose of this thread. The devs should change the way players interact with the asteroids as well. Perhaps a WARNING can show up on the HUD of the player who is within proximity of say 250m, for random intervals when the contents inside the asteroid become unstable and rupture smaller then larger spurts of superheated liquid ore.

This would take away the oppurtunity for afk miners to Heat roids to unusable temperatures other than long term mining, (over a day) and add a little something to the way that ore is mined.

Perhaps even add-ons can be invented for increasing the warning time for the player, or even some kind of temporary shield that has only a couple of uses, and is a heat shield, not a weapons shield...
