Anti drone is never ever worth it. Especially at the cost of shield upgrades. Those 2 extra shields negate drone attacks way better than anti drones. Anti drones if gotten for free are best used against the flagship depowered and still sitting right in the path of oncoming missiles.

Also pick either the pike or halberd, you don't need both, it's a waste of power. It's better to have some empty power slots on weapons cause they act as damage buffers for systems, your unpowered extra bars get deactivated when your system is hit instead of one you're using so you keep the system online. It's good to upgrade everything to level 2 even if you never power it up to there for that reason. Then 02 takes 2 damage to disable instead of 1, piloting is the most crucial for this so you don't totally lose evasion if hit there. I'd ditch the combat drone later on if anything better comes up or you're lacking in system upgrades. You can't aim a combat drone and they aren't good shield busters cause it's hard to time volleys with them. If you don't have hacking, cloaking or mind control, I'd sell everything but a halberd, burst 2 and letos (I usually save my missiles to take out the shields om the flagship so I can focus my first volley on taking out their missiles). Upgrade shields to at least 3 and keep 150 scrap for cloaking or hacking.
