Aight. I haven't contributed to this site since a long time, so I decided to write this guide.
PROTECTION PALADIN GUIDE
Introduction
The paladin is not always an easy class to level. However, there is an easy way to level fast and safely. If you spec correctly, you can take easily 4-5 mobs of your level and finishing the fight with almost full health and mana.
Pros
You have a lot of survivability. You can easily solo an elite of your level. With your bubble and lay on hands could also help you when you are in critics situations.
In pvp, you are harder to kill.
It is also possible to tank with this spec.
Cons
You kill slower than a retribution paladin with you fight a single mob.
You don't have any damage reduction against casters.
Buffs that you should have.
Let's say that you can really start to Aoe Grind before level 32-33. AT this point, you should be specced like this.

Essentials Talents
Redoubt
Damaging melee and ranged attacks against you have a 10% chance to increase your chance to block.
It is much better than devotion aura. WIth shield spikes and BoS, it will upgrade your damage done.
Imp. Righteous fury
Reduces damage done by 6%. It is useful because any damage reduction is good.
Blessing of Sanctuary
Probably the best talent in this tree. Reduces the damage taken and wil do damage if the paladin blocks an attack.
Reckoning.
Another strong talent. You will put judgement of wisdom or light on your target and the extra swings will give you extra live or mana.
Guide not finished yet. I'll probably give spot grinding spots and the effiency grinding technique tomorrow.
