Well, the flavor is awesome and reminds me of my own homebrew Paladin, the Oath of the Wild Hunt (which I recently shared here ) - but even the v2 is still way too powerful and would not be allowed at my table.

Resistance to nonmagical weapons as part of its first CD is way too much and really steps on the Barbarian's toes. The other CD is just a better, although slightly shorter-lasting version of the already powerful Conquest CD.

The Pack Tactics aura is something I had considered for my Oath of the Wild Hunt subclass, but also is way overpowered, as it results in automatic advantage as soon as there are two melee characters in the party (or one melee character and a summon).

THe level 15 ability makes no sense, as no paladin gains additional CD uses as their subclass ability, and it conflicts with general CD mechanics and multiclassing.
