Okay, this is rather random but I'm trying to put together a list of actual issues the Paladin class has. Not so much what we say as the root causes:
1. The seal system is good but badly excuted:
Too many seals either repeat themselves or do nothing. Seal of Justice and it's judgement are prime offenders. Judgement of Justice is rarely used because it doesn't do what we hope it will do. It's supposed to be a PvE snare but acts more like a stake and rope. As long as it's tethered to the Paladin then the bad guy will always be at range. It just keeps someone from out running us. It also has no PvP use. Instead of a useless snare, why not make it a four second silence? SoC is another Seal that has problems with implementation. It's intended to allow us to have two handed burst damage. But it is very unreliable burst damage. Instead of PPMs with it, turn it in to one shot weapon buff. JoC needs to not be tied to stun damage.
Seal of Crusader has it's own issues as well. The attack speed bonus does nothing. The judgement is excellent however. So perhaps in the spirit of us being buff bots, why not let us have a debuff. What if Seal of Crusader had a ppm debuff that lowered resistances by 5 per proc, lasting 1 min and stacking up to five times? Seals of Light and Wisdom are fine.
2. Purge and Counterspell
Two spells that pretty much make us useless. Turning seals into weapon buffs would help. But seperating our healing spells out of holy would also do that. If Paladin spells were nature based rather then Holy based it gives us two schools of magic and keeps us from being locked down any more then any other caster class.
3. Interaction
The controlled DPS arguement comes from this, not the more DPS arguement. The Paladin class is boring to play. The Aura system and blessing systems take up so much of our class skills but are mind numbingly boring. It's the downfall of any support class. The support abilites are such force multipliers that adding to us is game breaking. It's not DS that keeps us down. It's JoW, JoL, BoK, BoW....that is what keeps us from new abilites.
