I don’t know about anyone else but I think i’m seeing one 25 sigil pack every 50 bronze chests opened. Or perhaps even LESS. I haven’t seen one in a Gold chest either and i’m playing my game and my kids this weekend. Its pretty appalling and i’m not spending any $$$ as i’m not going to buy gold chests to have NOTHING of value in them (hardly any energy as well).
I hope this isn’t deliberate.
