[1.2.381] The Wind

Bishop damage doesn't increase nearly as much as other attacking classes. And even with increased damage, their attack speed remains on the low end (this is talking now versus post-jump where they attack faster).

And if your parties are like that post-jump in KMS, they're doing it wrong or you're doing it wrong then. Paladins always had respectable damage provided they fight elemental weak monsters.

You forgot my quote. :<
...and bishops get spell booster after Jump...

The reason people don't take Paladins as pure attackers is because a lot of their damage comes from elemental bonuses -- which a lot of bosses and higher leveled monsters don't give, and most of them resist elements, which make Paladins weaker.

I can do over 120k per Charge Blow on elementally weak mobs, barely over 55k on neutral monsters, and under 30k on resist monsters.

When compared to other classes in-game, Paladins are not nearly as powerful as they are on paper, unless given the perfect scenarios.

But either way, I've grown bored discussing this so I'll just say this.
People still main Bishops on KMS, and while yes, people may use them as just replaceable mules, that doesn't mean that a good Bishop can't be a contributing factor to a party past buffs.
