With Season 4 all about ground combat I was looking into respecing my Engineer to have more punch on ground missions. I would like to give my Engineering Bridge Officer a new ground skill to help with the combat, I recently found out that most of the skills that can be unlocked for training your Boffs are not upgrades at all, like
Support Drone Fabrication, Combat Supply, Equipment Diagnostics, Cover Shield.
All of the above skill listed can be acquired using the Bridge Officer Trainer on ESD,
And yet if I unlock the Turrets skill I can upgrade to Phaser Turret Fabrication III, why is that?
I noticed that the Boffs Support Drone no longer has shields and now has less hit points
