So you translate Challange with rng X rng x rng ...? ok. But that sucked.
Stacking layers and layers of RNG seems to be the only way people think there can be challenge in crafting.

In reality, its just a constant headache. Oh, failed a 90% skill 5 times in a row, thats certainly a reflection on my time investment or ability!

with regards to impact of shards and the like in the current era, its a forgettable annoyance and one of the few things I'm thankful gets botted to almost free on a lot of servers.
