So, in an attempt to get Toxic Brainz I broke down and spent 7 mil of my coin stash. (Really wanted to wait until another discount offer.) Anyway, I think I confirmed my hypothesis. Over the course of 135 35K packs I found that my average Super Rare yield was less than one per pack. (This considers Super Rare consumables as regular stickers.) Over the total of 420 packs that it took to find the complete Toxic Brainz (hmmm, I wonder what his toxin is...) I averaged a bit below 1 Super Rare customization per pack. (But, there were also ~12 Legendary stickers sprinkled in there.) With this in mind and the fact that most characters have 2-3 Super Rare items per type (Organics, Hats, etc.) then considering that each one has at least 5 tiers that need to be earned one after another I am very confident that a Super Rare funnel is the cause of the sticker decline. (So unless this was precalculated using statistics, it isn't a case of "Evil Company Wants Money.") Of course, I can't 100% confirm this until I earn and spend another 14mil+ but, I strongly believe when I get to that point I will find I have all the common, uncommon and rare stickers and the remaining Super Rare stickers will be fighting with consumables to be found.
