Okay, here's a random idea to help improve factional balance AND help us tank.
1. Take Fear Ward away from dwarf priests, and give it to Troll Priests.
2. Make paladins immune to Fear.
Now, Horde gets easy mode on bosses that fear. Instead of having to stance-dance, their priests can Fear Ward them like Alliance does now.
Alliance-side, because paladins are immune to Fear, they become a viable choice for tanking Fear-based encounters like Magmadar and Onyxia. (Or you can have a stance-dancing warrior, but the paladin has an actual advantage.)
This choice also makes thematic sense. Paladins are stalwart defenders of the light. Being immune to fear fits that vision of the paladin.
As well, it shores up one of our big weaknesses in PvP. Because of our lack of speed and range, Fear hurts us far more than any other class. A fight between a paladin and a warlock/priest actually becomes interesting now.
Edit: Okay, as the comments are indicating, a passive immunity to Fear is probably too extreme. How about a self-buff/debuff that breaks Fear and grants immunity for 10s, but increases damage taken by 10%? Maybe make it 'Unyielding Faith', and have the talent be "Improved Unyielding Faith", reduce damage taken by 2/4%?
