Playing League of Legends, me and a friend of mine are playing a Co-Op game, and he asks me where dragon is.
I ping where it is.
"That's not Dragon, that's Baron you moron!"
"Dragon is at the bottom, Baron is the big red skull"
He than proceeds to run into, and die to Baron.
"Why didn't you tell me that was Baron?"
Or, same game new match, but I'm playing as Warwick, and learning to jungle. I knew where the creeps are on blue side, but not on purple side. So I asked "Where are blue golems on this side? *pings spot* here?" Before I could get a response.
"OMFG you noob, why did you ping? The enemy can see you, they're gonna gank you now"
"You're an idiot, only our team can see our pings"
"NO! Everyone can see every ping"
"Than why don't we ever see people pinging that we're MIA?"
*He Rage quits*
These might not sound too bad until you realize we are both level 30 in these...
