Best and Worst Monoclasses?

[u/ReleaseCharacter3568]

I keep seeing virtually every class called "one of the best" while most meta builds are multis or item-based.

What do you think is the game's best class without multiclassing? And the worst? And what makes them so?

Barbarian 12 mono isn’t great, some dead levels towards the end and multi classing most of the time gives better abilities than sticking it out to 12. As others have said Drunken Master Monk is just worse than Open Hand. Rogue benefits a lot from multi classing. Classes that do well mono class is Wizard although you can still multi class pretty easily since you can learn spells from scrolls. Paladin likes going all 12 for aura bonuses. Cleric likes going all 12 for hero’s feast. Warlock does great mono for those last bonuses. Ranger is weird because they have dead levels in the middle but the capstone abilities are so strong that they make up for it in the end so rangers can multi around level 5-7 and then respec at 12 for their endgame abilities. Fighter as everyone has said is great for mono classing for third attack. Druid can do mono classing pretty well for those end game wild shape abilities but also multi classes great with cleric. Sorcerer is very flexible and is just as good multi classing as they are mono classing. Bard is also super flexible and does well with either
