From Gordon:
In addition to the throwing changes, a new ability (much more exciting than
throwing) is being granted to the rogue class. The ability, called ´┐¢Evade´┐¢,
is tied to the ´┐¢Hide´┐¢ skill. It is used by targeting a creature and
pressing the ´┐¢Hide´┐¢ button. If it is successful, it will dramatically
reduce how much the targeted creature hates the rogue. The Rogue will be
given a message indicating success or failure.

This new ability is, for all intents and purposes, a reverse taunt, and
will help the grouped rogue shift the targeted creatures focus back to the
tank after landing all of those hits. This is not like feign death, which
makes the creature forget you entirely, but rather just makes it hate you
less. In addition, it only works against the targeted creature.
