A Good Place To Fight Corpus Where People Actually Play?

[Damagedice]

I know of mimas, apollodorus, nuovo, etc for grineer.
Xini and such for Infested
Where does one go to fight corpus in defense or survival, where they are of decent level, where people actually play? Does anyone commonly fight the corpus, even?
What is a good planet/node?

Well it used to be Outer Terminus but it might be Grineer overrun... Oxium farmers you'll find in mid level planets playing defense missions, for the most part.

Invasions.

baal, europa is popular for oxiums from what i hear in clan and alliance chat

[Darzk]

Viver, on Eris, is a popular invasion for farming T4 keys, so groups go at least 15 waves, often 20.

Cerberus on Pluto, good XP and T4 keys.

Neptune, Europa, Eris, Mars, and if it's still partially Corpus controlled, Phobos are all Planets which you can normally find players playing the Corpus Missions on them.

 

 

in USEast that is, i don't know about anywhere else.

these 2. I like the map layouts (much more than the mobile defense, oxium farm sucks), and you also get T4 keys
