Gold packs (FIFA 17)

Do you think the difference in regular gold pack and premium pack affects the probability of getting a big star, I've revised plenty of videos with the opening of the promo packs, MegaPack, often just slag there is only a waste of money, of course sometimes there are lucky as the shark or 2дротсам. I myself in the premium pack had the Mower, as I think it may be easier to buy a gold pack for 5,000 many times?
