From today's update notes at playonline:
Blood Rage (WAR Lv.87 Ability Delay: 5 min. Effect Duration: 30 sec.)
Enhances critical hit rate and critical hit damage for party members within area of effect.
Warcry v2, anyone?
Personally, I'm a bit underwhelmed, but at least its still something new and useful, and certainly much better than nothing.
