Lucifier said: for me it looks it is cheaper than heroic, 40x is for 10kHP, in heroic it is more (even with daily discount draw).
Infrared said: The BFF bonus heroes rate has changed to 1:20 / 1:12 now. So was the good rate from before a bug? Was it a display error or were people actually pulling more bonus heroes?FWIW when I bought a BFF 10-pack, I got zero bonus heroes. I did get pull two non-bonus 4* so I guess that's still pretty all right.
