don't blame you for not remembering all of that
Well thank you for your absolution...not sure what I would have done with out it!

As for the condescension in your post, that seemingly, drips like puss from an infected wound...
...........I have a PHB, and an adequate memory.
Secondly, you have to get a proper run up
You just need a 10' run up to jump your STR score, (reduced to a 5' run up with the Athlete feat).
Thirdly, you can actually have more jump speed than your movement speed will allow you to use
Yup...so to sum up..the Oath of Glory has a Channel Divinity power that gives a character 10' bonus to both High and Long Jumps...and Advantage to Athletics and Acrobatics checks.
The Oath of Glory also gains a 10' enhancement to movement at 7th level.
So a 10 Str Oath of Glory Dexadin can jump like a 20 Str character.
A 10' enhancement to High Jump is immensely useful.
An Acrobatics check to not fall prone on landing is only needed if the terrain one is landing on is Difficult. Since a DM influences things like Ability Check DCs and if terrain is considered Difficult or not....it reads like perhaps either you or your DM, Leatherhead wants to hamper PCs that jump.
5e has lots of group support focused paladins, it doesn't need another one.
It does? How many Oath of Redemption Pallas do you see in play?
How many Paladin Oaths have effects that buff people other then the Paladin?
Elven Crit Fishing/Divine Smite Paladins with the PAM Feat
Is a Thing for a reason.
That reason is usually to do impressive amounts of single target damage.
Paul, you are suggesting, without evidence, that
every other Paladin Subclass is better at DPS
and "group support". While I understand that is how you feel, I just don't think the facts support the assertion.
Forgive my self quotation, but I think it important, that I restate this:
If you don't like jumping, if you want to be the most powerful, and if you don't want to take the Inspiring Leader feat, then this subclass is probably not for you.
