Your question is interesting.
First,define "roleplay",means to act as a character.
So different character have different styles.
In my opinion,Shoot the one who is too deserved a bullet in his butt instead of trash talking too much with him,help the one who are actually in needed instead of talking too much.
General speaking,be yourself,reflect the true self,I used to use chinese phrases and background when roleplaying a gangsters..do you think it is a good roleplayer?
