Last time I checked lasers were faster than drones. I found with practice I could crack a hatch faster without skipping a beat after dropping his shields.
IMO that is inefficient.
Here is how i do it:
You kill the pp first, to have tight cargo clusters.
Amount of cargo dropped is limited to health of hatch,
where drones can simply can be sent to break the hatch, as long as you have limpets,
leading to the maximum amount of stolen goods.
If you really want to hatch bust, you take a c1-beam laser and pulse it,
lowest damage in the game is what you want.
But that said I do see your issue... the viability of my tactic depends on how fast the fighter/mothership switch is once the fighters deployed. I mean if it's faster than programming a limpet we'll still have room to move, but I doubt it. Shredding the hatch? beams will be available for the fighter, with proper trigger discipline you should be able to milk three or four waves of cargo drops out of it, well that and a LOT of luck.
On the upside sending you fighter to aggressively engage security forces may by you more time than you've had in the past.
The fighter as a defensive module is a thing i look forward to,
but piracy and efficiency depends on speed and accuracy.
The faster you disable the target the more cargo you can cash in.
The firepower of the fighters is just too much for going into it and
"tickling" judging by presentations we have seen so far.
Security really has become a limiting factor, that is where the fighter may
increase efficiency in defense. What you forgot, is that your main ship or fighter,
when you set it to agressive simply will blow up your target,
also you cannot pulse your weapon/launch your hatchbreaker,
when you are in the fighter...
Piracy is not about destroying ships and hatches, bout about pure skill,
adrenaline and being a successful master thief, hunted by police, bounty hunters
and other pirates alike.
Piracy is the way to go, if you look for exciting fights and a challenge,
especially if you prefer PvE, that is as dangerous as it gets.
But back to topic...
