@Glomoro Actually
My views come from how the character archetype usually behaves in fantasy stories, and their actual usefulness in combat in a world that is not all black and while.
Paladins are ultra specialized, their powers are usually geared to dealing with enemies that are their direct opposites.
Which means that in a world of gray, they are actually pretty much useless against many enemies.
Just like how in Dragon Ball the Genki Dama is absolutely useless against the Androids 16, 17 and 18 or any of the Z fighters. Because it's an ability made to be used against evil and only evil.
An example of this is D&D, where you have many enemies that a Paladin can deal with properly and many enemies in which his abilities does literally nothing, making him into a weaker Fighter.
So, depending on the setting a good Paladin build could be high tier, or literally bottom tier.
The reason for that is because Paladins are not an actual "class" in most fantasy world's, you don't have an army of trained paladins.
Paladins are usually individuals chosen by a Deity or another powerful being to fulfill a specific purpose.
They are lent power to fulfill that purpose, they don't usually obtain it on their own.
Even in the setting of Warcraft(and not World of Warcraft).
Paladins were not that powerful, Arthas only changed sides because he saw the limitations of his powers.
And in his blind vengeance, he simply could not accept those limitations and try to work with what he had. Instead, he discarded his paladin powers and got what he thought was a superior power to fulfil his wishes.
