D&D 5E Help Me Choose a Character

[J-H]

As a side note, I went to a convention a few weeks ago and in the 3 games I played and the 2 others that my son played, there was only one arcane caster, a bard. I had a cleric in one and in another there was a trickster (mostly to get an owl familiar to grant an ally for shooting a bow and backstab.) Everyone else was fighter, paladin, or barbarian. The paladin only cast one spell and just smited the rest.

I guess it all worked in a 1-shot, but maybe not in a longer campaign.

My high level campaign (13-20+2 epic boons each) had some player shifts due to RL, but the ending party was
Vengeance Paladin
Fathomless Warlock
Samurai Fighter
Kensei Monk 18/Rogue 2
Only one full caster. Not a ton of healing either.

The original Castle Dracula party that preceded it was
Zealot Barbarian
Dragon Sorc (died) -> his brother, a Vengeance Paladin, who caught up with the party shortly thereafter
Arcane Trickster (died) -> Ranger (don't recall subclass)
Champion 3/Arcane Trickster X
Kensei Monk
Life Cleric
Only one full caster the whole length of the game.

None of my players make use of things like Death Ward, Augury, Scrying, Legend Lore, etc. etc.
But they all did fine anyway. Magic item availability helps keep things up to speed (Helm of Teleportation especially).
