Warrior/Knight Help Ultimate Support Paladin

I've wanted to try to make a sort of ultimate support paladin that exists solely to support the team instead of dealing absurd burst damage. Can I get some theoretical builds I could throw together that don't rely on Mythic items? Crafted items are fine, as long as it isn't something where an ingredient is only obtainable once. What would be the best theoretical skill tree to maximize teammate dps and survivability?

> has a lot of mana sustain for comfortable spellspam
> has 24k hp, allowing you to give a lot of heavenly trumpet overhealth (guardian still better for this tho, keep in mind)
> has rally for healing your teammates
> can deal up to 40 - 50k dps, which is horrible when compared to other stuff, but is just enough to beat lesser content alone if your teammate dies
