Most likely already suggested but.

Please add an NPC where one can trade male or female gear, in return for the gear of the opposite gender. It makes zero sense to be able to purchase a gender change and be locked out of specific event/one time gear. (Lightning for example)

So either an NPC, or all your male/female gear changes along with the switch of your gender. I think this is an important thing and it will encourage the usage of Fantasia Drinks. Thank you.
