As I said 16 kegs (fully milled and assuming you didn't get the card(s) you wanted) = 1 800 scrap craft. Since you (and other people) want to pay for them I doubt 16 kegs will cost you much (maybe like 16-18$ ?) while instead F2P gets around 3-4 kegs / day (supposing you play a sufficient amount of time each day). Thus you get 800 scrap in 4 days as F2P which in my opinion is a good amount of time, not too much nor too little. On top of that supposing all the kegs you buy have cards you don't want adn you mill them all it will cost you at least 60$ to get all gold cards but still...ALL GOLD CARDS! Gimme a minute while I calculate.....Ok so according to my calculations (and supposing that I didn't do any mistakes) to gather enough scrap through milling (without getting gold cards from kegs) would cost you (supposing you bought the 60 keg pack which is the cheapest at around 60$) *DRUMROLL*: approximatelly (if not less than) 540$. Which again is supposing you have the WORST of luck, such low luck you could be accidentally shot while walking in the street because a cop tried to get a bird away from his donut by shooting it and you were behind it. SOOOOOOOOOO yea I think it is ok if you make small investments from time to time and you will definatelly at sume point get a gold by opening kegs (even if its a double you can mill it for more scrap). At the same time increases the value of kegs without unbalancing the F2P-P2P scale.
