I belive th OP has confused everyone....I'll explain
Tier 1 Green's/Basic
Tier 2 Blue's/Protype's
Tier 3 Purple/Artifact's
Orange items are not in the Tier scheme, Orange merely denotes a Modable Item.
Crew Affection has not to do with the outcome of UWT missions, only missions with a tag of "Rich" will reward artifact/purple quality mat's
1. Please stop calling Purple/Artifact's Tier 2, For Armormech they are Tier 3 Recipes.
2. It is still insanely cheaper to RE from blue/protetype qaulity than Purple.....You can't relearn the same recipe twice so why RE purple...Just RE blue's.
