The rotations here are AABC every 5 minutes you can last. Do your best Tenno.
These endless missions, with infinite gangs of enemies, are good places to farm whatever you need. It depends on what you really want to get from them, the equipment you need to use, also the warframes you want in your squad.
If you want to last, Nekros will be so much appreciated, good loot and, the most important, more life support from enemies, don’t underestimate how useful can be (believe me I say it from experience). There are also some other good warframes, Nova, that can slow the enemies while increasing the damage they get, if you want to last as much as you can, Rhino to help every squadmate in trouble or even a Frost to protect the squad from ranged attacks.
The possible combinations are as limited as your imagination is. Let me know what would you choose to last as much as possible or to increase the loot the squad will get. I know that an important thing is to talk with your squadmates, see if you have a strategy, and if you are willing to play as a team or as a lone Tenno.
One tip, if you join a random squad, don’t expect that the target will be the same for all of them, or maybe you are the one out of place. If you are in the wrong place, you can always abort. Just remember there is always a way to do things easier, keep calm and think about the loot you can get if everything goes well.
Hope you can tell me more things about these missions, I’m eager for useful information.
