4story Gold, 4story Luna

There are several basic pieces of information and skills that you need to play a Paladin well. For those times you need to do something else, make sure you have a collection of gear either in your bank or bags that allow you to fulfil other roles. If you are mainly a DPS based Paladin for example, make sure you have a set of healing gear for those times when you might need it. Doing this will allow you to join far more groups that you could normally find if you just had gear for one thing. Even though you are not specialized in what that group is looking for 4story Gold, with the right gear you can be competent.
Few other classes that can take as much of a beating as a Paladin and none can do it as well on their own. Sure a warrior or Druid in bear form can have as much or more armour and health, but neither can heal themselves (unless the druid drops to normal form and takes a beating). As soon as you hit level 40 you are the only class other than warriors that can wear plate armour.
