Dont worry what others are saying. Paladin is a fine class and also good to heal. Get some higher ilvl gear and get used to your standart combo of Fast Blade/Savage Blade/Rage of Halone and you will be just fine. Your only problem right now is that everyone else is ahead of you(gear). So the other tanks will always be better then you. But thats just a matter of gear and you dont even need the best tank gear ingame to be a compatible end game tank. With the poethic tomestones (do your daily duty roulettes) you can buy ilvl120 gear wich is already enough to be a nice tank in lvl50 content.
