I used to be in a huge FMA roleplay group. I was a good roleplayer, who roleplayed a fanmade character who wasn't too overpowered but who wasn't too underpowered (despite what he was). I wasn't actually in the group, but rather someone who roleplayed with them in local (since I wasn't that active). But one day, my sister roleplayed him as a mary/gary-sue, and since that day, I never saw any of them again. I still hope to bump into them one day and apologize for that.
