I am in need of some help to improve my Tanking on my Paladin
At the moment i am doing ok, but i tend to lose aggro now and then. When i do lose aggro, i struggle a little to gain it back.

My Paladins level is 49

The Rotation i am using at the moment is:
* 1). Avenger's Shield - i use this to pull, and to control my aggro with 3 or 4 npc's
* 2). Judgement
* 3). Hammer of the Righteous - to help hold aggro
* 4). Shield of the Righteous - i use to DPS down bosses or I'll use * Word of Glory - if i need a quick heal
* 5). Consecration - Only use this on bigger pulls then 4 mobs, or on bosses

When i lose aggro, i don't know if i should use * Righteous Defense or * Hand of Reckoning

Also, which seal should i be using on myself?
* Seal of Truth (i currently use)
* Seal of Righteousness
or anothing one maybe..

I used a Talent Calculator, so i could show what I have at the moment (think it would need to be improved)

Also what kind of gear should i be looking for in stats wise?
I know it's Stam, Agli (i think), Parry, Dodge
But i don't know which ones i should focus on getting 1st.

So if anyone has tips / guides that could help me, that would be very appreciated.

This is my 1st tank, so I'm still learning
