I've never understood the purpose behind gender locked items anyways. Unique* ideas aren't always good, and this is a good example of a bad one. It's just an extra set of items that need to be added to the game. It's not even like the stats are any different.

*They had this in FFXI, and it kind of made sense a little bit with the RSE quests, but even in that case it would have been easier to just have a single item.
