Exactly - if a person is going to write a fanfic (in any genre) based on their fave characters/pairings - but can't (or won't) stay true to the characters - there's no ppoint in calling in a fanfiction piece.
I like the way how Sesshoumaru is; I hate reading FF's that's just.. ugh.. dissapointing to read him as some sort of a softy Eww **Twitches from fear** LOLz
AS for the FF's out there yea I agree when other(s) write a FF placing the character(s) in a role that just is not the same in the anime.
