Paladin Introduction and General Guide Pt.2

The protection tree makes the Paladin a better tank, giving better shield skills, better aggro gaining and such. You're able to build this tree up to Blessing of Kings, which is arguably the most useful buff you have. Healers and casters should not have this buff on, as mana and reduced aggro is more important, which depends on where you use it. When getting the Blessing of Kings, you can improve shield skills only if you want to off-tank a lot or get 10% more amour, who applies when you use 2h too.
The Retribution tree is bent on maximizing your damage output. You get the Seal of Command, who rocks when soloing. You also get 5% more crits in melee, 6% more 2h damage, 8% faster running and riding, better Blessing of Might, Repentance (stunning for 8sec) and such. This is the tree we recommend if you want to solo and level fast. Respec later if you want to.
You don't all the time have to max out trees if you like a decent mix. Blessing of Kings is good everywhere, so is extra armor. The Seal of Command is a must for soloers, and so is the damage. The intellect and strength increase is sure nice from the Holy tree. When level 60, you may think about respeccing to a pure holy Paladin or something, which depend on your play style. Holy is probably what you are needed for by your guild, and OFC Blessing of Kings
Paladins are normally underestimated in PvP. As a Paladin, you won't nuke them dead in 2 seconds, but you won't be nuked dead in 2 seconds by others either. What you have to be careful of is Hunters that use concussive shot and Mages that freeze and chill you. This is dangerous, as you can't shoot. By using a 2h weapon in PvP and with the shields and heals, Paladins are one of the classes that last longest in PvP. As a Paladin, we have managed to kill 3 equal leveled players alone in PvP by killing one, stunning, healing, shield, heal and kill and so on. Trying to do it, you will at least not waste too much time dying.
Paladins should not be tanks in instance. And not heal until high levels, as a Paladin who wants to level won't have holy talents. In addition, a normal Paladin below level 60 usually won't have all too high intellect, meaning low mana.
Things good about the Paladin in instance are the very diverse and powerful buffs and auras, and the fact that you are a hybrid, as mentioned earlier. If the tank loses aggro of a mob or a patrol comes from behind, there is no problem. The casters are safe, as a plate-wearing part-time tank can hold them off until the Warrior gets them. The Paladin can heal long enough for the healer to get some more mana. And if you're healing aggros the mobs, invulnerable bubble Blessing of Salvation Plate armor, there are many good ways to solve wow gold. With this, Paladins are very useful, even if they aren't damage dealers, super tanks or super healers. As long as you don't think you are any of them, you'll be fine. When not needed, just slam your 2h weapon in the side of some mob until the healer or tank can't manage their role. That is the time when people find that Paladins aren't as useless as they thought just because they are hybrids.
