Just 5 simple changes for Paladin.

2. This could be good however I still think that Sword oath needs to be stronger 50 potency is a joke for the "dps stance"

Sword Oath's passive effect is actually quite powerful, which is part of why paladin sucks so bad when it actually has to use a tank stance. Not counting the crit bonus from Deliverance, the 5% damage is actually giving you like maybe 13 potency per GCD. Sword Oath gives you somewhere between 53-60ish (just estimating so don't math me to death) depending on your weapon's delay. This is why warrior did so much more damage than paladin as a main tank in 2.0, but was pretty much even as OT: paladin gives up 50 potency per auto attack by going into Shield Oath and loses 20% damage. Warrior in 2.0 just took a 25% penalty, but gained access to a lot of new abilities.

I'd like to see them improve paladin stances by having them actually modify WS and ability effects, like how DRK gains health drain on Soul Eater and NIN switches its stun/silence. Warrior, also, essentially modifies its Inner Beast into Fell Cleave and Steel Cyclone becomes Steelier Cyclone. Plus it still gets to use its defensive abilities to increase its DPS because it gains stacks. So, some examples of what they could do for paladin:

Sheltron
Sword Oath: Gives the party member with the highest Max HP the use of your shield, blocking the next attack against them and restoring your MP. Activates Shield Swipe.

Shield Swipe
Delivers an attack with potency 210. Can only be used after blocking.
Sword Oath: Potency 230. Reduces the TP cost of your next weapon skill to 0.
Shield Oath: Your next weapon skill ignores the Shield Oath damage penalty and has increased enmity.

Cover
Sword Oath: Covered damage is reduced by 20%.

Clemency
Shield Oath: Cast time is reduced after blocking an attack.

That kind of stuff. The stances don't really need any buffs to their main effect (extra AA potency/damage reduction).
