In other words, if you want a tank, but you don't like a paladin do a warrior or a barbarian, but the paladin is "lawful good", and you have to accept that limitation.
I have play with the paladin and the warrior, and they aren't as powerfull as you say here, a ranger with his feats can beat them without many problems, the paladin or the warrior almost always will be melee chars, and the ranger usually is a ranged char, you can't kill what you can't hit. "
In other words if it's difficult, then cheating and ready no? <_<
