The Problem with Mini Achieves...
have you seen the golden achievement?
I would consider it an achievement to spend lots of gold. as much as it is an achievement to unlock all of a set of black lion skins, or run around and collect spoons from all the vendors. Any way you can think of to say ‘I was able to do this and you were not’ is an achievement. some are reflex-based. some are coordination-based. some are skill-based. some are economics based. some are endurance based (that one where you have to click your mouse for ~11 hours to consume like a million drinks)
I preferred the old achievement for these, where you just had to own them all at one time, then could sell them after getting the achievement. Then they went and added more achievements for flushing all the gold down the drain. gerrrrr.

None of the ones you mentioned are retired, proving my point. Adding new achievements instead of modifying the old ones to fit the new wardrobe system felt like a cop-out. So what about those players who never got a chance to save up all their gold to put the minis in the bank, or couldn’t find friends who would let them borrow some? Hello, ugly incomplete ‘Retired Achievement’ category.
Now if they had actually removed previous mini sets entirely from the game, then I would see the warrant for them to be made retired.
