"Just cast on yourself RAW lol" doesn't work because Rules as Written, each time you take additional damage, you take more damage. so for instance, a goblin hits you for 4 damage. because you now have resistance, you take 2 damage instead, but also take an additional 2 damage due to taking the same amount of damage. the problem comes when, Rules as Written, that extra 2 damage also causes you to take an additional 2 damage. now we're up to 6 damage, and it doesn't slow down. that extra extra 2 damage causes you to take an additional 2 damage, and so on and so forth. so, even if you can cast it on yourself RAW by wearing 2 rings, don't cast it on yourself unless you want any goblin to be able to casually one-shot your level 15 Paladin with 125 hit points.

One of my players is an Oath of Vengeance Paladin, and Warding Bond isn't showing up as a choice for him to take. He has 2nd level spells. Are we missing something? 

Only Oath of the Crown Paladins get this spell. You've probably figured that out at this point, but just in case.

Clarification please

With the person warded having resistances to all forms of damage which I believe means 1/2 damage, and with the spell caster receiving damage is it also the 1/2 damage? … and if the spell caster has resistance to that damage is it halved gain? 
example person being warded takes 20 points fire damage halved for 10 points due to resistance to all forms of damage, so that means the caster also takes that 10 points fire damage not the original 20 points right? And if the caster has their own resistance to fire damage it would be halved again to 5 right?
Or am I missing a major piece here?

 But you have resistance to all damage.  Starting with 4 damage, resistance makes that 2 initially, plus WB damage for (initially) 2 more. That 2nd set of damage is resisted down to 1. And per the PHB rule on rounding down (https://www.dndbeyond.com/sources/phb/introduction#RoundDown) when that 1 is applied to you again due to WB, it gets resisted to 0. Total damage taken: 3.

So if you self-target, you get +1 AC, +1 to saves, and take slightly less damage.

 You've got it.  Note that the spell doesn't inherently give resistance to you as the caster, so you probably need to find resistance from somewhere else.

It doesn’t have a range of self and is not an area so you cannot cast it on yourself 

Quote from Owynjr >>

Situation:

- A wizard drinks a potion of invulnerability. This gives resistance to damage to the wizard.

- A paladin casts warding bond on the wizard. This gives resistance to damage to the wizard. Also, each time the wizard takes damage, you take the same amount of damage.

As always resistences do not stack nor count twice (this is not what the question is about). The question is about rules as written versus intended. 

 

A damage dealer deals 50 damage to the wizard.

Resistance only counts once. So I am expecting that 25 damage will be resisted, and nothing more. 

Rules as written:

- The wizard is dealt 50 damage. Because it has resistance, the wizard takes only 25 damage. 

- The paladin takes the same amount of damage.

Total damage taken: wizard 25, paladin 25 = total 50

If the paladin did not cast warding bond, the wizard would also take 25 damage, because of the rrsistance granted by the potion of invulnerability. Total damage would be 25.

But now, because warding bond is cast, the paladin also takes 25 damage and the total damage to the party taken is 50.

Netto effect of the warding bond: 25 extra damage.

Is this the intention of the warding bond spell?

Or is the intention of warding bond that the damage taken by the wizard, so 25 (the damage that reduces the wizard's hitpoints), is distributed (split) over the wizard and the paladin, so they each take 12.5 damage?

My take on the matter is the latter. The paladin absorbs half of the hitpoints loss because of his bond. That is what is intended (and the original spell in earlier additions got a bit botched by an ill chosen application of the resistance mechanism). 

 

 Most contrived situation to make this not excellent protection option. This spell will give the wizard +1 AC, +1 Saving throws and resistance to everything, decreasing the chances of taking that 50 damage(which you didn't cite a source for so im assuming melee hit, which might've been prevented by +1 AC) and the damage taken. You neglect the +1s and focus on the resistance and negated it with a potion. In this extremely niche circumstance, yes you take 25 extra damage. Otherwise, it is splitting the damage and giving bonus defenses, as intended.

 Turn on optional features in character creator first page and turn on extra paladin spells under optional features on class page

Oh wild. Super MAD though

Artificer subclass that gets this spell as part of their expanded spell list feature

This depends on which the DM decides applies first. If the invulnerability potion applied first the paladin would not take half the damage, but if Warding Bond applied first they would. That said if the Wizard already has a source of resistance there is no reason to use the spell on them in the first place.

Neither does "cure wounds" are you suggesting you can't touch yourself?

The true cost of this spell is all the marriage jokes your party will make.
