Paladins have always been broken and i agree that they need to be changed..
Highest life of all chars with 1600ish more base and 50% extra per vitality point.. (compared to most classes)
They have insane speeds, defense, +stats(which has again become quite relevant with the charms nerf), lifesteal, invulnerability(x2),
DR, decent summons, 2x teleports, resistance pierce and on top of that a newly dinged pala does more dmg then many classes do with 500 sigs and a decent equip (50% sus or so..)
