Your RoP change is not correct. You still have the section which was changed.
Ring of Peace Forms a sanctuary around the friendly target, causing all nearby enemies within 8 yards to be disarmed and nearby enemy players unable to auto-attack. In addition, enemies who cast a harmful spell within the ring become silenced forinstantly silencing and disarming all enemies for 3 sec. In addition, enemies who attack or cast spells on allies within the ring of peace will be disarmed and silenced for an additional 3 sec. Ring of Peace lasts for 8 sec. Monk - LvL 60 Talent. 40 yd range. Instant. 45 sec cooldown.
So it should blanket any caster/healer for 3 seconds regardless of casting anything, then reapplies if they cast after it is done. Pretty massive buff, and probably too strong for a 45 second cooldown. I assume they took out the auto-attack portion due to the bugs with pacify. Though this will allow melee to interrupt while in RoP which does balance it out in a way.
