Can we just talk about how the M+ "Depletion" is not working like Blizz said it would?

So, first off, this is how Blizz (Lore Specifically) said not finishing a key in time would work from 7.2.5 on:If you complete the dungeon but don’t make the timer, you’ll get a Keystone for a random dungeon that’s 1 level lower than the one you just used.If you don’t complete the dungeon at all, you’ll have a Keystone for the same dungeon that’s one level lower than the one you just used.So, I have run multiple dungeons this week, and seeing how difficult getting to a 15 is now, I have depleted many of them (probably, like, 4-5 at this point. So I highly doubt it is bad luck.) EVERY SINGLE ONE that has not been finished on time has been turned into the SAME dungeon 1 level lower.That is specifically not what Blizz was going to be the case. :[
