Yo,
Well I unlocked all my legendary character pieces from the 15k packs also, and because you get more bang for your buck so to speak its best to stick with 15k. Once you've unlocked ALL hats, silver, gold, diamond and gem versions and you're left with nothing but legendary hats and consumables then you might want to try your luck with the 35k packs.
That developer obviously doesn't know what time it is, either he's been misinformed or even the packs are bugged. Either way, buy the 15k packs 🙂
Maybe he wanted you to spend your coins quicker to increase coin sales? ^^
I'm pretty sure that since the patch they completely broke the legendary stickers from packs, though. I got Iron Citron and Disco Chomper from the packs before the patch. since the patch, I've spent several million coins on the zombies pack and the 15K packs, and still nothing. Pretty sure they broke it along with the party Rose. I'm actually beginning to think that they artificially extended the life of the game by making some of the pieces impossible to get. Knowing that they weren't going to have any DLC out in the near future, they decided to make it impossible for us to be able to get a few stickers so we would come back for more. Just a nice conspiracy thought, though.
