As for looted armor, it can be easy money to an extent eary-mid game, if you know how to manipulate your selling. But come into the Rin section of the game (by then, credits should be abundant), armor is non-existant when it comes to selling them. No stores will pay Rin for player-useable armor so unless there's better armor in loot than what you already have installed, it's senseless to even loot it.
I personally have to dissagree with this. Doing so would take a lot of fun and enjoyment away from playing the game. The majority of armor I use comes from loot.I suggest that they should be destroyed and not possible to loot from wrecks.
Perhaps if we lowered the amount of survived armor in wrecks would be better?
