Well that’s not fair…

Why is cosmic class the hardest one to get in terms of drop rates? Just give me a cosmic so I can rank 3 my 7* Galan when I get him from my titans or basic crystals 😭.

Hilarious, but also weird. I will inquire. In the meantime, just be aware that after you open your first 5000 of those, you might have one fewer cosmic on average than intended.

You pay attention to the most random stuff.
Good job!

I have verified with the devs that all six classes have an equal chance of dropping, and the very tiny drop odds discrepancy is a visual error, not a drop weight error.

What the system appears to be doing is that it is calculating the drop odds of every single drop except one, and then presuming that the drop odds of that last item is simply 100% minus all the other drop odds. This ensures that the visual drop rates reported actually add up to 100%, which of course they should. Since the drop rates are not short decimals, they are getting rounded. As a result, what is 16.666..% repeating is rounded to 16.67%. So five of those combined have a net reported drop percentage of 16.67 x 5 = 83.35%, and the computer is reporting the last item as having 100% - 83.35% = 16.65% drop rate.

This is purely for humans to read. The way drop tables actually work is with drop weights, not drop percentages. When the devs want to make a crystal have an even chance of dropping any one of six items, like here, they simply create a table with six entries, one for each item, and set their weights to be 1.0 (usually). That makes them all even. The computer then adds up all the weights and rolls a random number between one and the total. In this case, between one and six. Each drop is assigned one number (its a bit more sophisticated than that, especially when different drops have different drop odds, but that's the gist). Whatever the computer rolls, that's what you get. With six numbers all equally likely, the classes all have a one in six chance of coming up.

So the crystal is fine, the drop odds are slightly wonky due to a combination of round off error and the desire to make the reported odds properly add up to 100% (which they mathematically would have to if they had infinite decimal precision). You will not in fact see one fewer cosmic rank up gem every five thousand crystals.

(re: unquoted analysis above by DNA)

So, the system was rounding the numbers first, then adding them up, to subtract from 100, to show the last remaining number, which isn’t really the last one, because it was the first one displayed, and for some reason is not in any correct circling on the class wheel anyways (although it is if you go alphabetically, but why would they need to sort the classes alphabetically, instead of a known class order), to show the percentages in some confusing order, which would lead someone to create a post about it, even though the unrounded original numbers would actually be used by the random number system, to generate your rank-up gem, which would then be complained about anyways by some, because they have a certain class of champ, that after several pulls in a row, they still don’t have the class gem that they need for that champ, so it must be rigged anyways, as evidenced by a 0.02% difference, which means if that 0.02% error is possible, then who knows that it isn’t even more rigged, because we are never shows the actual code, so that we could know for sure that crystal drops aren’t rigged, of which why would any company ever show their user base their copyrighted proprietary software code for their main point of income, just to be knocked off by some unscrupulous 3rd party software company, to release an essentially duplicate game, just like many companies, and Amz itself, do when knocking off a companies product.

Wait, how many comma's before it's considered a run-on sentence ?

And, story inspired by other common mis-complaints about crystal drops elsewhere in forums recently.

(Point 2)
At first, I was just gonna chime in and say “well, imagine they listed ALL 6 percentages as correctly rounded to 16.67%”
And then someone else comes on and writes a post saying “How can percentages add up to 100.02% ??? yet another problem with crystal odds”, lol

Could have changed it to 16.65 for each and the remainder a generic gem?

I like that idea…

Don’t be silly. That would be way too generous
