More than excise, I want consolidation of a few options that step on each other's toes. The Undying Patron should be excised because it's essentially telling the same narrative as The Undead and can be considered consolidated there. I want The Hexblade Patron consolidated with a more vigorous Pact of the Blade (make each of the Pact Boons more vigorous, without requiring Invocations to pump them up).
I want Death Cleric and Grave Cleric to be a single Death Domain option that can add necrotic damage to weapon attacks or to potent cantrips. No need for a Good Death Cleric and an Evil Death Cleric. If you're going to use Death Domain to mean Slaughter and Pestilence and the horrors of war, maybe you need another domain like "Destruction Domain" or something.
I want Arcane Archer to be split into Arcane Archer and Primal Seeker, utilizing the Arcane and Primal spell lists to some extent respectively.
