The Problem(s) with Paladin

[Duelle]

It's kind of funny though, even with rock wall archtypes they had capability to do decent damage in Final Fantasy games and most other MMO's and RPG's out there, and SE seems reluctant to try it with PLD/GLA though they're designing all it's game mechanics to work with a damage = hate mentality.

This. Tank DPS matters. It's always mattered, but people took a long time to figure it out. It wouldn't be a problem if you restricted all tanks to a one-handed weapon and a shield, but when you start tossing in two-handed tanking and so on, you realize that unless you even the playing field again someone is going to be left out. That's when developers realized tank DPS matters.

Quick fix for Palladin. Give a holy buff/skill to the sword. And throw some undead mobs/ bosses.

This won't fix anything, and I say that as one of the ret paladins that massively benefitted from undead mobs in Naxxrammas and Icecrown Citadel. Being situationally better on a mob type only prolongs the innevitable.
