Worst thing you ever did to another player here or on live

[Pootle]

Not really a 'worst thing' but waay back in Luclin/PoP era I was in a guild who were kinda known for messing around on raids sometimes.

Telling all the new guys in the guild to click on the 'Electric Penis' in PlaneOfStorms to get their 'raidKey'.... then half the raid would be in hysterics as the statues came to life and killed them all.

One gnome /split a huge stack of copper in Vex Thal during a raid-crawl just as the mob gravity-fluxed everyone into the air. His whole group hit the ground HARD.

Always kept the whole guild laughing on those long raids.
