So I've found that doing Rockcliffe is pointless.
99% of the enemies give literally 0xp, 0 money or close to if any, the ship battles MASSIVELY nerf you with no way to get substantial, and you get fucked over because "AH HA! I had a connection that had literally 0 signs of existing, therefore I win." and that's the entire ending of it.
You spend a few hours doing fetch quests, get 5 h-scenes max, and a shitty gimmick battle you can farm for a tiny benefit and armor and weapons weaker than the area before it.
But I mean, if you like getting cucked go ahead.
