Clerics on D&D aren't healers like in a mmo.
They are representatives of a deity in the material plane. D&D is not the generic mmo about gear farming and cooldown managing. The spell system for eg, is based on literature(Jack Vance). And necromancers are a wizard specialization, you have evokers, abjurers, conjurers, illusionists(...) 5e already has the weakest necromancy on D&D franchise, with a single summon limit, there are no reason to even have it on the game.
So Clerics are basically "John Wick's" for their Deitys huh?
Well - I truly didn't knew that. And it feels very wierd just the same.
There was always a fine line of distinction between a user of Holy Abilitys and well, yeah... UNDEAD UNHOLY ABILITYS.

ARE YOU KIDDING ME?! ^_^
NECROTIC HANDS?!
A TOTALLY EVIL SOUNDING SPELL!!

THIS IS NORMAL?

FOR CLERICS?! ^_^
Why destroy the Unholy for your Deity if you can become the user of the Unholy? Makes no sense to me.
But I somehow matches our current real world political climate. So much hypocrisy!
( Not going fully there though. )
I expected something different when my Cleric represented Selune just for the luls to piss of Shadowheart. And she took it way more easily as I expected.
The gods can suck d... -evil then. LoL
After factchecking this piece of shame called Kelemvor I feel like Devils are the better deal anyways.
This mofo imprisons people because they lived freely without SIMPING to a god.
Ok, its war.
Peace was never an option.
(LoL)
