Recently went back thru Moria with an alt, loved the changes and re-enjoyed the mines all over again.
During an Orc battle my alt got a 2nd age drop, it was really kool and made my day.
Areas after Moria these days require you to make 2nd agers, which takes away the enjoyment IMO of discovery.
Im not asking to takeaway anything from crafters, but i think there should be a small chance to still find 2nd agers from drops, whether its only elites/sigs or what ever. But discovery/surprise is far better entertainment than making IMO.
Just my thoughts.
