I managed to get at least one of each in 80-something pulls. Now I'm just pulling so I can maybe get Akafuyu to max pot and maybe get at least one potential for Kal or Skalt, but I'm pretty much tapped out.
Two Kals, enough copy of Greythroat to max her potential, 3 Akafuyu and other 5* after probably 7x10 pulls, plus more pulls up to now. Update (as 11/3 night): Holy S- it's 4 Kals now!, max potential Akafuyu and...still no Skalter. Sad.
50 rolls. Got all three of the new operators. Including Skalter. Much better than my previous roll for Rainbow Six Siege banner which made me do 180 rolls to get all of them.
No Warfarin from this banner, but I did get P3 Akafuyu (a fine prize; I like her quite a bit already), and got Kal. This annoys me a bit, as she was the Operator I was ambivalent about compared to Aka and Skalter. Still hoping to pull Skalter before the event runs its course, but it'll be tough.
Already had Warfarin but this banner got me the opposite result of what happened with me trying for W and Rosmontis. As in, while I ended up going pot6/5 for them respectively, I ended up with pot3/5 for Skalter and Kal. And one dupe W.
This is like the first banner where I didn't get someone 6* who's available regardless.
147 pulls so far, 2 Skadi the Corrupting Heart, 1 other. I guess it's not as bad as Mudrock release (130, 1 Rosmontis only), but I'm sad Kal did not come home yet.
