yea, you guys are posting as lower lvl's, i posted above as a lvl 6o, because at lvl 60 you will be doing loads of high lvl instances, and you need all the armor you can get :
Retribution tree :
-----------------------
Concecration : is a must for multiple aggro.
Seal of command : will make sure you kill a mob in short a time as possible. Some people take seal of righteosness, bad choice, seal of command does tons more damage when it procs.
Conviction : will give you a 5% increase crit rate.
Vindication : will reduce the agility and strenght of the mob by 15% for 10 seconds and procs fairly often, almost on every mob for me.
Two handed weapon specilization : is a must, it will push up the damage of your weapon quite a bit, and despite what anyone says, you will use 2 handed most of the time. specially when you solo.
Vengeance : this is extremely usefull, if you crit against a mob you will for 8 seconds afterwards do extra damage, and most fights don't even last longer than 8 - 10 seconds, so if this crits you will probly for the rest of the fight be doing 15% more damage.
Eye for an eye : half the mobs you will fight are casters, and they will constantly do spell crits against you, with ey for an eye you will return 15%- 30% of the damage back to them when they crit.
Deflection : this will increase your chance to parry an attack by 5%
Improved blessing of might : at lvl 60 you will constantly be buffing the raid group, and you want to give as much attack power to whoever you buff, so even if you use kings and not might, it is still essential to have this maxed out.
----------------------------------------------
The above talents are all in the retribution tree, and are essential to any paladin, the rest is optional, but i can't see how anybody can give these talents up.
----------------------------------------------
Protection Tree :
-------------------
Improved devotion aura - This is a must for any pally, since you will often be fighting 60+ elite mobs at high levels, the higher your armor, the longer your health stays up the less mana you use to heal yourself, the more mana you have to heal others. This is a Must !!!!
Precision will increase your chance to hit, the less he will resist, parry you, the more you hit the lower the mobs health will get. this is a must.
Toughness is a good talent since it increases your armor and goes hand in hand with devotion. optional talent, but a must for me.
Blessing of kings is a extremely good talent to have, it increases your man, health and all other stats by 10%, how can anybody not use this ?

Holy Tree :
-------------
this is a extremely difficult tree to place talents into, since i prefer to be a damage dealer rather than a healer, i would prefer to put majority of my talents in the retri tree, so i take my last remaining 11 talents and put them on the talents i will use most in the holy tree.
Devine intellect , even tho i like doing dmg, i end up healing alot in high level dungeons, and increasing my mana is a must for this reason.
Devine strenght, this will increase your strenght by 10% and as a dmg dealer you want to get the most out of your swings.
Concecration, with multiple mobs this will often save your backside, trust me, every paladin should have this.
--------------------------------------------
Even tho i would like to put more talents into the holy tree, i just can't get myself to sacrifice any of the others above, My survival comes first, then everyone elses, who is gonna resurrect everyone if i die ? if the priest does not heal then it is not my fault, and you can bet your @ss he will die before you, he is a cloth wearer, he often goes down on every second or third mob because he pulls aggro when he heals. My job is backup healer and offtank, i assist the warrior that is tanking, and if warrior dies or is not present then i tank. if priest runs out of mana i take over healing.
This is my build, and it is a good one, i really can't see how anyone can go with different talents, altho i come accross alot of noob pallies ingame that end up diying more than the priest, most of the time they are holy / prot spec pallies, they can heal real well, but can't deal damage for sh!t. thus dragging a fight out for a minute longer than it should last. the longer the fight the more damage you take .....
this is just my opinion, preference will differ for everyone, but my point of view is from a lvl 60 experience. it is really different for lower level's, since they solo and quest more, where i tend to run dungeons in large groups most of the day.
my current stats as a pally are as follows :
-------------------------------------------------
Lv: 60 ( my second lvl 60 pally, last one was on friends, before i got my own account, sad because he had full epic set

)
Suit : complete blue set. gonna start collecting my epic set this coming week, again

( this set has no enchants on it, it is standard, i just don't think it is worth enchanting till i get my epic set. )
Stats :
--------
Strenght : 226
Agility : 101
Stamina : 286
Intellect : 157
Spirit : 176
armor : 7132
Health : 4061 ( before buffs )
Mana : 3377 ( before buffs )
Min Damage : 349
Max Damage : 448
DPS : 120.7
Attack Power : 761
Crit rate : 13.01% chance to crit
Parry : 10% chance to parry an attack
Dodge : 7.81% chance to dodge an attack
block : 5.00% chance to block attacks with shield.
That gives me 22.81% chance to block, parry, or dodge an attack
This is my pally with the above talents, i want to see anyone who thinks he will take me down easily come and give me a try, i will whip your @ss so quick you won't know the fight has started. Especialy rogues, i love dueling those guys ...
if you can get past my 7k armour, my 4k health, my constant healing, my 500 - 1200 dmg blows per hit ( and i wont even go into my seals and judgements, or my undead spells ) , then you welcome to try, i don't understand how people can say that pallies are only good at shield / hearth, i have never had to do it, if anything the horde are allways running from me. I stun him and 6 seconds later when he recovers he finds himself with only quarter health left and standing inside my little circle of consecration aura, when he runs, and they allways do, i fling my magical hammer of wrath that will split him in two. I am sorry, but there is no way in hell that a cloth or leather wearer will beat a plate wearer, if you do then you duelled against a real noob who does not know how to play his class.
