Less of this.
Paladins may not have as much outright dps as fighters or barbarians (though a good KoTC is definitely up there with most), but every paladin is capable of using divine righteousness to generate incomprehensible amounts of threat.
Paladins might be down slightly in hitpoints compared to a fighter who spent feats on extra toughness, and moreso to a barbarian, but the paladin's saves makes it relatively easy to avoid half of all incoming spell damage while the lay on hands means a momentary lax in healing doesn't transform them into the latest soul stone.
Paladins can also reach reasonable levels of intimidate without any particular investment from the build, which goes a long way in terms of getting the boss sorted quickly.
Paladins make fine raid tanks.
As do specific monks and rangers, though it's likely to take them more effort to overcome the hp dip.
Less tank discrimination please.
