If you see a person that is obviously fighting towards a node, leave it alone and find another, they are everywhere and what purpose does it serve to be rude? Absolutely none. Retail is rude enough. Being rude in Classic may just earn you a notable bad reputation on your server amongst other players, which can quickly spread to guilds and that you do not want. So people might want to reconsider before engaging in rude behavior. There seems to be a lot of people coming back for classic that haven't played in a long time like me, and the game was not filled with rudeness back in the day, like retail is today. Just a tip you might want to pay heed to.
