Okay im playing up an Arms warrior (lvling most in BGs) and ofc i have "Unrelenting Assault" 2/2
"Reduces the cooldown of your Overpower and Revenge abilities by 4 secs and increases the damage done by both abilities by 20%. In addition, if you strike a player with Overpower while they are casting, their magical damage and healing will be reduced by 50% for 6 sec."
But still havent seen it place any debuff on an enemy, ofc hard to see if it have been on a single time in bg but havent seen it in bg or outside.. Is mobs immune to this or what?
On wowwiki it says
"The ability also causes a curious bug with Revenge. When Revenge is enabled, this talent allows you to repeatedly spam it until it is disabled. When tanking as Arms while leveling, use this to your advantage."
and just testet it, and that seem to work.. 5 revenge on a single dodge..
