Alot of my wow pet peeves are actually outside of the game.
Super Nationalists: Ok, WHO CARES if the guild who got a world first was from an Eu or US server? and both sides are guilty.
Mass QQ: Ok sometimes, yes Blizz does wrong, but man. EVERYTHING they do is met with constant whining. Hearthstone is now 30 minutes, seriously? people actually complained about this change? YOU BETCHA! New druid form art? ITS NOT PRETTY ENOUGH! WHERS MAH BOOMKIN!? WHY ARE THE NE ONES PURPLISH? Ok, have you been to Teldrassil? THE FREAKING SKY IS PURPLE, everything is purple, and alot of NE's are purple. So thus, yes, theyre forms are indeed purplish.
The word Bads: OK PEOPLE, LET ME TELL YOU ABOUT THE DIFFERENCE BETWEEN ADJECTIVES AND NOUNS! You see, words like bad are adjectives, and meant to go with a noun, thus describing the noun! so say the noun is player, then you get BAD PLAYER! But no, thats too much, so people are using adjectives as nouns, seriously, everytime somone uses bad as a noun, an english teacher cuts themselves.
There are many more but I'm not in the mood to list em all.
