Best defense missions for farming and ranking?

[Rontemon]

What are the best defense missions now for farming MODS and RANKING UP?

My friends and I play on Io on Jupiter a lot. It's an infested defense with only 2 ways for them to get up to the target. It can get a bit tricky when disrupters and healers come, but it's not too bad with the weapons and abilities we have (Dual Ether Swords (x3 damage to infested), dual heat swords (x3 damage to infested), and javelin on exaclibur (can easily 1 shot a large group of disrupters/healers). We typically do 10 waves and get anywhere from 8-15 mods depending on how often they feel like dropping

Once you can handle it Kappa on Sedna is the place to be.

It's Mobile defense but you'll easily net 15k (sometimes way more) XP per run and usually 6 (again, sometimes way more, I've found 13 before) Mods.

It's best do farm with 4 people and things go berserk. You'll kill 500-ish enemies as a team by the end.

in mobile defense mode, faster you kill more they come. with the best group i have ran, we ve killed 200 ~ 300 mobs each (4 of us) and earned 20+ mods and 50k exp.

+1 for Kappa on planet Sedna. you not only find a ton of mods, you can farm rubedo and alloy plates by the dozen, which are sought after materials

Yeah, Kappa is great for farming if you can handle it. Screenshot from yesterday farming:

Yeah, Kappa is pretty much THE place to get mods, exp, rubedo, and alloy plates.
