You must enjoy to defend random things that would never say “thanks mate, you did a great job”. If so, you’ll find all those places here, just with one glance.
*As I told you in the General Map, the Defense mission Io in Jupiter is the best mission you’ll find if you want to farm Messo Relics. It is because the Corpus enemies you’ll face won’t cause many troubles, and you only have to endure 10 waves (rotations A).
On Defense missions, rotations follows the same pattern AABC, as you’ll find in other missions. Don’t look at me, I’m not the one who created this system!
Defense Missions used to be considered boring or slower than other options to farm good relics. OK, these missions can be boring in some cases, but they are, in my opinion, the most effective ones. Think about how much time do you need on other missions to get Relic rewards, and also the rotations, you may do and repeat just to get the same chances for relic rewards.
If you want to increase efficiency you have some good options, Banshee with her Augment Mod for low level enemies, Quick Nova and other powerful warframes depending on the enemies, etc. You’ll find your own way.
