So ive finaly come around to share this, in mount hyjal theres some npcs called Hovel Shadowcaster(s) that cast
Curse of Recklessness Curse
Melee attack power increased by 45.
Armor reduced by 290.
Ignoring fear effects.
2 minutes remaining
IIgnoring fear effects.
This will stick on in the arena, ImageShack® - Online Photo and Video Hosting, bit bad quality, but you should be able to see it.
So if you're playing with a disc / paladin healer you wont get it dispelled, since they dont take curses.
Also this cant be dispelled by the other team, so this is pretty big vs RLS, WMS and RMP's, which all rely a great deal on their fears.
Also, beware that you need to leave combat somehow before you can enter arenas, but a invis potion or just by making them run back, the mobs miss quite alot, so it took me around 20ish second before I got hit by a curse, but on a good day thats still 1 min of fear protection once the gates open
Hope this helped someone!
Quick edit; location of the mobs http://www.wowhead.com/npc=39643, they're inside a cave
