Detect Traps

Detect Traps allows a rogue to find traps laid out by others. It is learned at level 42.

When paired with Disarm Trap, a rogue becomes essential for the safekeeping of any band of dungeon explorers.

Tips and tricks

 * Of particular use in Stratholme to identify legitimate supply crates.
 * Allows you to see hunter traps in PvP.

Controversy
Many rogues expressed great displeasure over the change of Detect Traps to a passive ability in Patch 1.11. They claimed that they enjoyed spamming the "Swirly Ball" (a reference to the old casting animation), and now have "nothing to do during buff downtime at raids". Despite the many complaints, Blizzard has yet to make a formal response.

Other rogues also claim not being able to see a hunter's traps, nor being able to disarm them, until it is too late and the rogue is caught in one of them.

With the addition of Glyph of Detection in patch 5.0.4, "Swirly Ball" has been brought back.

Trivia

 * Detect Traps is a Rare Rogue ability card in the World of Warcraft: Trading Card Game's Drums of War set.
