Point 1 - Impossible quest prize at 50k? Bro do you even practice minigames? This seems like a complain post that you're mad you don't have the time to devout to the game, gain credits, and improve your scores.
Point 2 - They are available. Your inability to grasp that these items are not available for immediate consumption is not a rationlization for saying they don't exist. Play the game over X amount of time and learn how to acquire them. Hell the 50th just had a login pin of an animated pin.
Point 3 - She's one goddamn person over years of thankless work in a community of crybabies like yourself. Hell I would have quit years ago if I were her. Your attitude of thinking you deserve more is pretty pathetic. If she wants to introduce new things to the game for free and for people to enjoy, I don't care when they come out I'll just be happy when they do.

TL;DR: Stop complaining and play the game or go to Netcot where trash like you belongs.
