In the past I've also read of people (though, they were nice people talking about themselves) that thought that because it said "Greed", Greed was the bad role and they didn't want to seem greedy, so they hit Need. Which has predictable results
I don't remember if the Need vs. Greed system is explained in SWTOR, but then, even if it was, people wouldn't read it. It's rather a pity that companies are having to code their games in such a way as to diminish the detrimental effects of some arse who thinks he's being funny.
And no, I don't have any good "bell-end needing on Cunning gear while a Juggy" stories.
