Wisp Spirit

Whereas other races run at normal movement speed as ghosts, this racial trait causes dead night elves to turn into wisps that move 75% faster. This can be really useful in grouped world PvP in which you are able to reach your corpse and resurrect sooner, eat, Shadowmeld, and be ready to fight again faster. It also helps recover from wipes in dungeons slightly faster, reducing downtime.

This ability improves in certain zones in Northrend. Whereas other races use a spectral gryphon in Icecrown and Storm Peaks, the night elf turns into a flying wisp which moves faster than the regular "ghost mounts".

Many call this racial ability "Improved Death", mocking night elves for having a racial ability that is only useful after dying, rather than something that is useful to prevent them from dying in the first place. The ability is situationally useful, however, and unlike many other racial abilities it benefits all classes.
