Not sure where your math is coming from. There are 86 days left in the season and you get 100 Tix every day from the item shop. That means you can get 8600 tix without doing a single challenge and just logging into the game every day and going to the item shop. Daily challenges give you about 250 a day. So if you just collect your tix in the shop and do the daily challenges, that's 31,000 tix. On top of that, you have weekly and monthly tasks and challenges that give Tix.
I think the game is gonna have the opposite problem, everyone is going to have everything unlocked in about a month and then get bored.
