That's the reason why I go for the champion. My paladin has INT 8 and is for smiting evil, not for making tactical decisions. ;)
Usually I play wizards (in some more complex RPG than D&D), so champion is just fine vor this campaign and for this character concept. And there is already a dwarven...
I'm considering to dip into the fighter (champion) with my paladin (planned paladin 16/fighter 4).
I've got the Shield Master feat, so I can hope to knock the enemy prone and use the advantage for crits and the improved divine smite for extra damage dice to double.
Since one can spend spell...
