It would't be a benefit, because drones should be able to be configured to be as useful as possible. A group of 5 drones with the firepower of 10 would make easier targets, but also have a better success rate of destroying their opponent first because of their increased damage.This system would kill off slow vulnerable drones with big guns, which I believe is a benefit
It's all about tactics mate, restricting options that aren't broken means taking away tactical strategies of attack/defense and overall making a more unbalanced game.
and I'll reiterate as well, seeing as turrets are better with stronger guns, they will also be nerfed, which is a bit unfair to ships that rely on turrets to take out more mobile threats.
