Credits from Ops

[Duck Person]

Can you reliably farm credits in Operations? If so, what ships are best?

[Nepgear]

Yes, but it's not as good as it used to be. High damage tier 8 premiums like Mainz, Bayard, or Kaga are best. Unless you're top of the scoreboard it's not very good.

a lot of new to ops players means you don't win as consistently as you use to but you still make good credits

[Stainstein]

You 'have' to be good to get good amount back. Get all the 'objectives' if you can and survive as long as you can while supporting teammates (that matter, not the yolo or scaredy cats). It's a mixed bag, but when you get good at it, you also get good at randoms.

[ReDiR]

Irian is very good too

[christof]

It's decent, but not great. Better than Coop on a per battle basis for sure. Not necessarily on a per time basis though, since playing one takes about as much time as three Coops.
If you're working with consumable bonuses, you're better off with Operations. When going without, you might be more efficient in Coop.
