Faye was originally meant to be a sort of antagonist when I made her back yeeeeeears ago for a forum RP. It worked in forum RP, where the scale was smaller and I had an endless list of characters I could alternate between if I really pleased. But in an MMO, it's difficult to main an antagonist--especially when you lead a guild IC and OOC (and a good-aligned one, at that). Needless to say, the Faye I role-play now is far from the original character concept. I do miss the more antagonistic, less humanized Faye and hope I will have a chance to role-play the character or something similar again... but at the same time, I'm all right with the difference because I know the changes were made for practicality and convenience for the setting in which we're role-playing.
On the other hand, I had another character who was supposed to be sort of tragic, so I threw a lot of hurdles her way in her backstory and her storyline. ...unfortunately, it just so happened that all of the people I role-played with also seemed to have a desire to throw a lot tragedy her way. The character became miserable, selfish, and depressed to the point she was emotionally draining to play and so unfriendly, misanthropic, and stand-offish that getting interaction on her was near impossible. I didn't want to outright retcon her, so I pushed the story in certain directions I knew would make the character more bearable, and it worked well enough (though is still sort of a work in progress).
