There has only actually been one badge I wanted to get and I got it, so I'm going to not care about the stickers anymore.

I know completing one set gives a reward, but considering there are 10 sets, it feels like another pull to get people to keep playing due to FOMO.

Maybe if others also start to just look at the stickers as extra, and not something to work for as a reward the devs will bring it down a bit? Not sure if the devs will see that people have stoped caring tho.

I do believe it used to be too easy, now it feels like you have to do all events completely perfect to get even close.

I know this is not an airport, but I'm done with the stickers now.
