Currently if an orca pilot is overseeing a ore mining operation the orca pilot can mine just about as much as an exhumer but if the orca pilot is overseeing an ice mining operation the orca pilots mining via ice drones is only about 1/3 or so of an exhumer.
I realize the the orca has better boosts for ore mining than ice mining but that is little comfort to the orca pilot overseeing ice mining operations.
So, please increase the ice drone mining benefit on the orca to 75% reduction in ice drone mining duration.
Or… Decrease the ore mining a bit. It should not be keeping up with a fully boosted exhumer (assuming it is since you haven’t provided info on boost levels, barge mining speed and orca mining speed here)
It actually should in my opinion because the rorqual took over ‘core’ mining in nullsec and the orca should take over ‘core’ mining in highsec (should someone want to risk 900+ million mining in highsec that is).
The tank on the orca is better isk per ehp value than the hulk or mack. And since it is a drone miner it doesn’t lose its low slots to MLU either.
So it most certainly should not also get better yields as well. Otherwise exhumers lose all reason to exist.
