For the first few months, a hundred packs would normally return a profit. for the last 2-3, it's normally a loss. Obviously that figures when you consider that some cards are worth as little as 10% of what they once were. But, it would be cool if odds could evolve a bit to reflect the dropping market. I know it's tough balancing economics with gameplay, but it's frustrating having pack ripping gradually becoming less rewarding.
I've definitely been consistently getting more live silvers recently, so the Devs can clearly tweak things if they see fit
