I always hated "Fear" cause how annoying and OP it was. Well it wasn't the fear itself rather than you running about like a headless chicken rather than cowering in one place.
Anyways, Ring of Peace seems to take the cake though. Not only is it on 45 sec CD, but it requires no skill. Shockwave for warriors were nerfed cause of its AOE stun and that it required not much to be done for something that big.
How is it any different from Ring of Peace? You are basically locked down for 8 sec. To top it off, if you get caught in a Fists of Furry, you are basically locked out for most of an entire minute before both these come of CD.
This is currently the most annoying ability in the game and something needs to be done about. The CD should at least be 2 mins for an ability as OP as this.
