I will point out that the commends with reaction bonuses are kinda hard to attain with a loknarr. Let go through the list.
Electrifier: Kills with electric & emp, not so easy when most of either group is non lethal until a fair ways into the game. EP ammo is needed before you could start in here with reasonable weight for a lok, Muskets/Air musket with SC ammo could be used but the ammo problem of that line of weapons is compounded by low weight capacity
Chaingunner: 3 kills in a turn with bullets or lasers, several times and only +3 total reactions. Not necessarily very difficult but conflicts with Electrifier above.
Samurai: 8 kill in a mission with melee, not something loks are particularly great with. Need fairly advanced/specific weapons in the right circumstances. Poison dagger counts so that probably the best bet, but animal poison can be hard to come by.
Street fighter: This ones pretty juicy considering it's a loadout that favors loknarss, but 40 kills before you even see the first rank is a fair wait. 40 kills with comparatively puny arms takes awhile.
Triggerhappy: This one is the most likely, but they all need to be in the same mission, which hinders how high it's likely gonna be. Loknarrs are not well suited
for prolonged exchanges of fire. And there are very few encounters you can just farm without risk.
Bullet Magnet: +2 possible if you have been shot at a few hundred times, and somehow not died as a loknarr. It could happen but not the kinda luck i want to push. I will also point out gal of steel is -reactions and usually accompanies levels of bullet magnet.
There are 2 others Super size and avenger, but the former is +2 after alot of exp gains, and the other is posthumously awarded.
So while it is possible to get that magic threshold loknarr pilot again, it is not what i would call easy. And many ships have multiple pilots required. How many of these super aces are you likely to have in practice?
