[2020] Did Enhancement Rules Change Again?

With the last big update, they made the common enhancer break everything it fails on, but the unlicensed got a lot cheaper. Then they nerfed common breaks so that no failed enhancement attempt below legendary would break.

I just now failed enhancing legendary +4 to +5 4 times, and not a single break. How are we supposed to know what's going on if they keep changing the rules without saying anything :p
