9 chests. 5 to 10... All 5s. Really???

chest 5 to 10 - only 5 rune
chest 7-10 - only 7 rune
chest 8-10 -only 8 rune.

Why would you expect anything else?

The only guarantee with any of the chests is that you will get the crappiest result. I always get the worst possible outcome from these. The only way to get the decent runes etc is to actually pay for them with real money,don’t think for a minute that a “lucky chest” or a level 5 to 7 rune chest will result in anything but the lowest possible outcome

If you‘re lucky, than you might get a Level 6 rune, but that‘s it.

The really interesting thing to me is that lower level chests have good results. The cutoff is the 2-4 chest.

Earlier this week I got FOUR IV runes from my 2-4 chests. But as soon as you open up the 3-5 or higher chests, it's bare minimum almost every time. I am positive that if I kept track, my average haul would be higher for the 2-4 chests than the 3-5. It's kinda crazy.

I get it. It's SP. They're gonna do what they do. I'd just argue that I would have WAY more fun with these dungeons if there was an element of randomness to what I won. Accepting and predicting the minimum turns it into an incredible grind, where I just do the math thinking "ok 2 dungeons per week times 4 dungeons per month, times 6 level 3 runes..." and then it hashes out to like, ok, 3 months of dungeons for a level 9 rune. Or whatever. It's demoralizing. Predictability is not a good quality for a grind game.
