Easiest way to get paladin in diablo 4?

paladin is in diablo 4 now, it came with the lord of hatred expansion, and pre-ordering that unlocked it early. so the easy way is just owning the expansion, then it's on character creation. base game alone won't show it, which is probably why some answers still say it doesn't exist.

paladin isn't a class in 4, so there's nothing to unlock - you're thinking of diablo 2. nearest in feel is probably a barbarian, or a necromancer if it was the support side of it you liked. worth glancing at the character creation screen before sinking an evening into a build guide, because plenty of those guides are written for 2 and never bother saying so.
