A few (poor) screenshots of the animations for new 5.2 Rogue abilities and talents. They weren't joking about trying to give us more visual flair.
Mark for Death:
The rogue points at the target, a skull similar to the Mortal Coil ability marks the target's head... FOR REMOVAL!
Hit and Run (Cloak and Dagger scrapped?)
First image: The rogue blinks to a targetted location, becomes basically a living shadow-bolt. A still image doesn't do it justice, because about 6 or 7 Shadowbolts become physically attached to your body and leave a trail as you go.
Second image: The Rogue's shadow is on the left. On the right, for comparison, is the Transcendence of the nearby monk.
Shuriken Toss:
The Rogue's autoattack animation is replaced by their "throw" animation for 10 seconds.
Per the fabulous Ichifails in Post 9 of this thread...
Slightly edited for formatting and such.
