I feel that this is being glazed over by so many pulling the 'this is an MMO, female charterers will always have sexy armor' card is that this is not the bulk of what the OP wants. There are plenty of nice skimpy armor for you to put on and glamour for your characters. No one is saying 'no more sexy in my game at all'. What is being requested is that an iconic piece of gear, that is the primary representation of a specific job or class, is not drastically altered for the sexes, theme wise or look wise. This set is suppose to represent Dark Knights. It does not need to be glamed up or dolled out for any reason.
Having a piece of gear better form a character is welcome in my opinion is makes logical sense (hence why so many were upset about the Noct Loct armor on females, although in my opinion it only looked good on fem/male roes, highlanders, and some catboys.) But having a piece of gear fit a character better does not mean redesigning it to show skin (al la Dragoon belly AF style), or making it more sexy, or glamorous. That's why as a few have noticed there are slight differences in all the AF armor between the males and females but only the Dragoon one is complained about extensively.
A number of other games do this well where a female character is given armor and it is entirely warped by any means, it just fitted to their figure without changing the fact that it is well thought out functional armor.
There is a time and a place for sexier gear, or gear that is more feminine between the male and female characters, but iconic tank gear(similar to the WAR and PLD sets) is not one of them. There will be plenty of other sexy gear released in the future, but I have faith they will leave this set's design alone and just properly fit it to both sexes unlike that scary Noct Loct.....man those abs were frightening. @__@
