Let's talk about the challenge log.

This was the same at the begin of HW the formula capped at 50 and just at a later point i don't remember when it was updated.

So it is likely intentional. It is a minor point in the scheme of things, but I feel like it works into the larger picture of levelling alts requiring piling together disparate sources of experience that sometimes just don't pay out very well. I am seeing signs that the math is breaking under the stress of experience from 60-70 being more than double that of 1-60, with fewer time-efficient means of advancement. To which I ask why?
