you gotta have terrible rng not finding one on ptr, I literally encounter 15+ heralds just clearing act 2 and every monster can drop it too not just herald.
nah its just you got lucky... its like a "bunch" of people claiming they found multiple HRs in 1st week of ladded and run drop rates are too high - what you don't hear is the 99% of folks that aren't that lucky. Just because you got lucky don't mean its suddenly too easy to get sunders for everyone else.
