The one path in the Rifts that is a bit nonsensical
Nonsensical is a strong word, however, I do think that there is a problem with one of the random Rift paths in the Legendary Rifts. It is the sig stone path. But to get there requires a bit of math. Aw, who am I kidding, even if it didn't require it, I would still force you to read it. Might as well get it over with.
There are six paths other than candy in the Legendary Rifts. They award 2M gold, one T5CC crystal, one +5 6* sig stone, two T5B cats, 10k 6* shards, and one 6* AG. What are these things worth? Well, we can look to the Candy store itself to get an idea. I'm going to specifically be looking at the Cav+ store for this comparison.
You can buy gold. 200k for 20k candy. So 2M gold is worth 200k candy, according to this valuation.
You can buy T5CC via fragment crystals. Five 2% crystals costs 5000 candy. So a full crystal is worth 50k candy.
You can buy T5B, one costs 10k candy. So two T5B is worth 20k candy.
You can buy 6* shards. 650 costs 15k candy, so 10000 is worth 230,769 candy.
You can't buy a 6* AG. But I'm going to state almost certainly without controversy that a 6* AG is worth way, way more than 20k candy.
And then we have +5 6* Sig stone. We can buy that in the Candy store for 7k candy. Notice that every reward above is worth at least 20k candy. Some are worth vastly more. But this path contains a reward that is, according to the Candy store, worth less than the 20k candy you would have gotten on the default path. It is the one "lucky" path where your rewards can be reasonably said to drop.
Now, there are advantages to landing on this path. If you want sig stones, you're limited to only one purchase in the Candy store. Landing on this reward might be a good thing, relative to what you want. But you could say that about every reward. This reward is the only one that is generating a lower reward than the intrinsic economic value of the 20k candy you'd be getting on the default path. That seems weird, if not wrong.
If it were me, I would boost the sig stone path in the Legendary Rift from one +5 sig stone to three. This would then make the economic value of that path 21k candy, and at least marginally higher than the default 20k candy path.
I'm not saying the Rift is "broken" per se. Maybe they deliberately wanted that path to have low value because sig stones are still so high in (design) value that they needed to be constrained to the point of assessing the value of getting two instead of one have an outsized qualitative value.
But if it was me, I would try to make sure every single non-candy path contained a reward that would at least pass the eye test as being worth more than what I lost out to, and the sig stone path in the Legendary Rift doesn't do that, and I don't think 6* sig stones are sufficiently constrained these days that this was compelled. Just my opinion.
