I think that if a person has done certain insanely difficult dungeons an x amount of times (like Darkmoor around 20 times) it should give them a badge and unlock an ungiftable version of the good gear from there for around 15 thousand crowns. It rewards the players who went through lots of pain going through Darkmoor-like dungeons a huge amount of times. Note it isn't pay to win because at this point they deserve the chance to buy the gear (seeing they ran through it around 20 times all the way up to the very end)
Examples
Waterworks King 10 runs of waterworks
Greek God of the Sea 15 runs of the poseidon dungeon
Ruler of the Undead 15 runs of Tartarus
Darkmoor Emperor 20 runs of Darkmoor's final dungeon
