I’ve tried to protect my Miner, while he’s working on an asteroid, but there doesn’t seem to be an effective way to help him out.
Parking a combat fighter in the asteroid field has no effect. Either or both of you can get pulled into combat. It seems random. The rate of being pulled into combat seems the same. I found that my miner was lucky to get about 3 or 4 undisturbed mining cycles before getting pulled away.
Actively having your combat toon attacking the enemy at the asteroid field also does very little to protect the miner. The enemy spawn replacements as quickly as you kill them, and the miner gets pulled away just as often.
A couple of ideas come to mind, (assuming protection is something that is desirable for the game). The enemy attack percentage could be altered based on the combat ability of the mining team. Or the spawn rate has to be slowed down so that killing the enemies means it’s safe for a while.
