I actually hear the word heel used quite often in the fgc. I also hear it used in some sports talk shows as well. I've never heard anyone say "I'm gonna be a villain and post this savage post." I have, however, heard the term heel used many times in scenarios like that. To each their own, though.You feel that way because your comparing the FGC to movies and hollywood.
Look at the word fuzzy. You can fuzzy block (guard) your opponents mix ups. But the word "Fuzzy" doesn't mean the same thing in the English dictionary. Villain is perfect to describe what we are trying to say - it's simple and understandable even by new comers as it hints towards what we are trying to get across. No one actually thinks they are actually villains (that would be silly) because this isn't a comic book strip.
Also the word villain has been in the FGC for a while now it's not just something unique to players in mk or NRS games for that matter. It definitely isn't gonna change now.
