The next update isn't actually revealing any more information than the game already displays, it's just giving it to you in a nice compact form that's much easier to access, and in the case of SoU it's showing it to you before spending the scroll instead of after.
Unfortunately I don't intend to show off accuracy and evasion stats because the numbers aren't particularly meaningful. The hero has 10 accuracy and 5 evasion to start, and gains +1 of each per level. This tells you nothing about the actual hit/dodge chance on a per-enemy basis. the only real way for me to show this information would be to show the exact hit/dodge chance for each enemy, which feels like way too much information.
So an evasion augmented armor grants 4 + 2*lvl evasion. I could include this stat, but it's not actually going to help decision-making at all, as you have no idea how that compares to the amount of blocking you've lost. Furthermore extra points of evasion/accuracy aren't necessarily more useful, generally the more of it you've got the less useful each point is, which is often the opposite of blocking's value. So I just don't include the numbers at all as that ends up being a similar amount of information with less complexity.
Accuracy figures are the exact same in this regard, I'd rather have no numbers at all than show numbers which aren't actually useful.
