I have already shown that a level 16 human paladin with maxed out strength does less 1H damage than a level 16 human fighter with maxed strength and Weapon Foci + Weapon Specialization Feats. If the developers add the Weapon Mastery and Weapon Supremacy feats then Paladins will fall by the way side, unless we are given the proper spells to compensate for the disparity. Paladins have nothing that even compares to fighter melee haste, and don't even get me started on Barbarian Critical Rage. I for one don't want to play a fighter or barbarian, and I believe my class should get the attention it needs and deserves. If you like fighters and barbarians that's fine go advocate for them, but don't beat down paladins any further into the ground.
Barbarian vs Fighter vs Paladin
