I think he means that to increase gas harvesting efficiency with drones CCP would nerf all gas harvesting to keep things balanced. So you would get reduced efficiency of current ships and get about the current efficiency if you used the new drones as well.
something so many people never realize just take missile for example. we told all the people asking for missile guidance mods that it would only result in a missile nerf and that’s exactly what happened. not only do you need to sacrifice more to get the same application but there are missile disruption mods too.
its simple unless you can make an argument as to why people should be able to mine more gas adding these will only mean you now NEED to have the drone to get the same amount of gas
Moving a large ship to the fringes of a cloud IRL to harvest the outliers would be inefficient, drones can not get those dregs you could not get before.
