I have no time for MMOs anymore but I'm the support class.
I remember being a kid playing Ragnarok Online as a Dancer (a girl-only class), because my guild needed one for certain spell combinations. During guild events people would always refer to me as "she" in voice chat and I didn't have a mic to correct them, but I also kind of liked it for some strange reason.
And of course since I already have a girl account, I might as well also make a sage character - the mechanics are good but also her dress is pretty...
MMOs were a very trans experience for me.
