If you're a minion collector and are whining about this, your resolve is weak and pathetic.

If you say it's too unlikely to even try to get the top 10 rewards, didn't you think about how unlikely it is for you to get all the minions ever when you decided to start collecting them?

Either you decide that you're going to get all the minions and at least try, or then just accept that you can't get all of those minions ever.

Did you think you'd get all minions if you just drop some cash?

If you want it enough, you'll put the work in to get it.
