Is there a difference between proper gear for the two specs? I ask because I'm using the same gear for shadow (which I use when questing or dps'ing) and Discipline (which I use when healing). Up until Northrend, I healed pretty well, although I didn't do much. Now, at level 73, I'm having a hard time healing UK and Nexus. I'll link my armory, maybe you smarter than me people can tell me why? :). Thanks.
