Step 1: Cast trap
Step 2: Make sure you run out of the effect on the ground just as it spawns. You need to run out and get the buff, but just barely.
Step 3: Infinite 50% speed!
It's been like this since 5.1 came. Anyone know if it's still like this in 5.2 on ptr? I find it quite useful. Also, is the glyph of direction still removing the CD of Misdirection in 5.2? Because I've learned that having no CD on MD is quite great, actually. Should be baselined :3
Ah, the joy.
