Paladins need to actually be Paladins.
Right now they're more like...well, nothing, really. Giving a job a bunch of defensive cooldowns doesn't make them a Paladin. A sword and shield doesn't make them a Paladin, either.
They need magic. Holy magic, to be specific, that's actually USEFUL. We can use Protect, Cure 1, Raise, and Stoneskin. The only one that's really useful ever is Stoneskin. You'd never use Protect or Cure 1 during battle, and Raise is only out of combat.
Come on, these aren't Paladins. -.- We should at least get some kind of awesome self-heal with a 90-120 second cooldown, or something, and maybe a unique party-wide heal with a longer cooldown (doesn't have to be a full heal like Benediction, but something decent). Also, there are plenty of undead/evil creatures in the game. Why not some attacks that do extra damage to them?
Gladiator/Paladin was my first 50, and I played it for a good 2-3 months, and the fact that they don't even feel the slightest bit like a Paladin just helped turn me away from the job.
Most of the attacks/skills just seem so generic and not very Paladin-esque at all.
