My paladin tank is 85 and very well geared but i have only one problem. Even though I'm well gear i still take a ton of damage even in heroics. I read that avoidance is important too and that i should keep parry and dodge close to each other for diminishing returns. Most of the damage i take is block but i rarely dodge or parry. i reforged and regemmed my gear recently and these are my current stats right now please tell me if I'm gearing right: dodge=13.04% parry=15.10% block=58.13%

That's because paladins are built that way right now. I'm sorry to say you may just want to reroll until they fix prot paladins. You will be doing us healers a favor.
