I think if we did a poll of those who have completed it all it would likely be the same to be honest - might be wrong but there is no benfit to players to go through tougher farming - most of which is difficult to auto for one reason or another when the gold itself is worth less than NotB or AMOLAD/Powerslave. I get that NC need to be tough and it sort of was but for players who are really trying hard to beat it and get the skulls etc surely the rewards need to be greater than what went before it - at least in terms of gold/ironite/SoT etc - I get that you now can have newere talisman that many may not have but most will have several sets after they complete it so wht go back unless you need to for an event - same with all the other areas. Other than farming when do we need to go back to them other than for an event maybe or a particular accomplishment or mission or to level up characters.....a bit of a waste of resource that I think is easy to improve by adding the extra difficulty levels.
