I will repost this from another thread, mostly because I am interested in others opinions...
i dont think the premiums are worth it anyway, unless you only want ultra rares. They are ~70% more than spectre, so the math...
6 premium spectre packs - 600k
12 guaranteed rare
30 total items
10 spectre packs 600k
10 guaranteed rares
50 total items
But wait, there is more. You have a 6% chance in the other slots in a regular specre of pulling a rare, and a 5% chance in a premium. But in the regular you have more slots, so...
there are 40 "possible rare" slots in 10 regulars, giving a 240$ chance you will pull more rares in those 10. If the random actually worked, it would be on average ~12.5 rares out of 10 packs, or 25 out of 20. In the premium you have a 5% chance of pulling a rare in the open slots, with 18 open slots in 6 packs, that is a 90% chance, or roughly an extra rare per 6. So out of 6 packs, you should end up with roughly 13 rares, or 26 per 12. So out of 1.2 million credits spent, (12 premium or 20 regular), you get a whooping 1 additional rare, and 40 less items.
This all asumes that the numbers I have are accurate (no way to know for sure either way, just what I have read online:
https://docs.google....tIdFFOR0E#gid=0),
AND that there is some normal randomness to the system, which there clearly is not. That said, I have pulled rares in vetran packs and 2 in regular spectres, so the chance is real.
The real issue for me was how many premium spectre packs I have opened and gotten 2 character cards (opened 4 in a row and got 8 characters, 4 of the same, so clearly not random). I am probably off, but it seems to happen less in the regular.
This brings up another point. I am about done with MP. It is just so difficult to get decent weapons, and I dont have the time nor do I know anyone who farms. The game setup clearly favors those who play all the time and invest heavily in credit farming. I realize for any game the more you play any game, the better you are/ more fun you have, but this is for the gear that makes the game fun and interesting.
I really would like to explore the game more, play gold matches with a decent setup, play around with the different weapons, but thre is WAY too much time required to get to that point. It is exaclty why I could never get into Call of Duty. the game so heavily is skewed towards those who spend all day long building up their weaons and perks, it just doesnt make it enjoyable to the casual gamer who cannot invest that kind of time.
