Mine would be:
1. It's an MMO so if you don't do group content, then quit and play a FPS.
2. World quests take 5 mins max so it should only take you 30 mins to do all your world content every day.
3. Gear from "MY" source should be higher than "your" source since I work harder and it takes more skill.
4. The Majority of Players (and then just make any statement to back your opinion)
5A. The game is easier now than it has ever been.
5B. The raids are harder now than they have ever been.
Lots of games being played outside of the game being played.
