I guess you could use:
Teleporter + Reconstructive Teleport augment
Clonebay + The augment for preventing crew members from being lost when it's destroyed
To make invincible boarding parties?
DNA bank isn't that great if you just be more careful with your boarders, but I guess it's insurance in case you lose both the teleport and Clone Bay
In any case, I feel like killing enemy ships with a boarding party should yield better rewards. It feels kinda underwhelming when I'm getting the same scrap and items for sending my precious crew members into dangerous territory, and not only that but it also takes way longer to kill a ship off with a boarding party than it does with weapons or drones.
Clearing out enemy crew does yield you higher rewards. Most ships upon destruction are Low/Medium Rewards. Boarding gives you Medium/High rewards.
Also, I found that boarding can be quicker than your guns if the enemy has high shields and evasion. Boarders don't miss.
Or maybe a boarding party could have a higher change of finding drones/weapons? I mean, if you kill the enemy crew and take the ship intact, why not get better rewards seeing as how nothing should be destroyed on the ship?
Well if the enemy ship is carrying cargo, you're more likely to retrieve it intact.
