I get alot of whispers, mostly good ones but also some negative from time to time. Have tried alot of different things to the hate whispers, and it seems the "nice day to you too" reply works the best, most times they feel bad and appologize. But some people are just plain stupid - i ignore those.

I remember about a week ago outside Orgrimmar (Brew festival place), got a few hate whispers again. Then a party of alliance showed up and started nuking people. I was at a distance so they didnt see me, ran behing a tent and started nuking them down one by one, until the entire party was down (BT/T6 gear) - my 5 shamans was lvl67 by then. People target to cheer and laugh at me (possitive way), guess it was because i had the balls to face them, even when i was undergeared and 3 levels below them. They resssed and i killed them again.

I left the arena about 5min later and got the crying/sad emotes from the other players.

Nice to get some possitive feedback from time to time
