I have just got to level 85 on my paladin, but the healers in my groups (normal dungeons) find it very hard to keep me alive. I have 4 epics. Because I die fast I cant get justice points to get gear

I have (with out any aura or buffs) 3820 strength, 99 agility, 5613 stamina (121k hp), 578 mastery 11.22, 6.12% hit chance (735 hit rate), 26 expertise (794), 29690 armor (reduces 53.25%), 6,85% dodge (321), 30.26% block

Please tell me the Priority and Cap for the heroic dungeons.
This was in a dungeon, so i had that dungeon buff

Make sure all your gear is plate >.> <.< also use a shield ^_^ . But also pay attention to the dungeon mechanics, mobs and bosses have things that can kill you if your not careful. The dungeon journal is out now so read the parts on boss attacks, its right next to Dungeon finder. Make sure you have a profession that allows you to enhance your gear, JC is good as well as smithing and also reforge your stuff if needed, stam is good for your sockets but not all of them. Dodge and parry is a plus when reforging. As for you epics... make sure they are tanking epics.... haste crit and hit only plate pieces is not tanking gear. If you must, heal yourself... pally, or worse case scenario use one of the shield abilities that does not remove aggro. Also stay out of fire! That is all XD
