Hello there,
so previous featured 5* crystal, I had a feeling like all those newer
featured champs I'm actually buying it for somehow eluded me. So when current 5*Featured hero crystal (and look at the menu-it is one good looking crystal!) was released, just for fun, I collected data. And I know I may be just one small sample of the majority, but here is what I found out:
This game is now like 6 years old. Strictly statistically speaking, there is 24 champs in the crystal-if you aiming for specific champ, having 24 crystals (24 tries) is a good chance to get him. I had 26 featured 5* crystals.
As the pool of this crystal was set this time, chance to get champ released between 2018-2020 (newer champ) should be exactly 50:50 with chance to get champ released between 2015-2017 (older champ). And yet:

Not only the chances are nowhere near to what one would expect, it actually scales down almost perfectly with the years of release. Looks like you are much less probably to pull newer champs-those actual
featured champs you buy this thing for in the fisrt place!
Last featured 5* crystal, it could have been just a feeling. But now, based on data I've collected, it is very hard for me to believe those crystals actually aren't rigged in favor of pulling older champs. I believe in math much more than in honesty and especially in this game. And this math seems to be rigged.
If that's the case, shame on you, Kabam... I guess I'm done with featured crystals, you know, fool me once and so on...
