I bought one pack when I got the game a few weeks ago, just to try it.
Then I got 11 packs from the Twitch Drops and in those 11 packs I got one 87 Gold Player. Every other player was something like you got there, with some 60+ mixed in.
I always wondered, why I should buy packs, when I can get at least one much better player for the same points.
I'll take free packs from the Twitch Drops but I don't see a reason to buy packs for my points. Selling the cards doesn't even get you the value of one pack.
Anyway, just wanted to add my two cents...
