If they have the dps to kill afk orca’s they would most definitely kill T1 mining frigates and barges very easily which would make it not friendly to alpha players.
I tried to look at that corp but it was empty.
That really depends on how they’ve coded it in the first place, because it could be as simple as throwing in one method that would throw a class randomizer in there to identify which ore would be selected per drill cycle and then calling that method every time a drill cycle is started. As I said though, that really depends on how they’ve coded it, as it could be even more complex.
