TBH though is there any reason NOT to go support with your Paladin tank in Deadfire?
My points went into passive abilities, and they all seem worthwhile:
Deep Faith (+10 all defenses)
Retribution (+5% damage with weapons)
Weapon and Shield Style (+6 Shield Deflection, Shield Deflection bonus applies to Reflex)
Divine Purpose (+20 All Defenses vs Resolve, Dexterity or Might affliction)
Snake's Reflexes (to boost my Reflex, because from ability score bonuses I'm only getting a +4 from the 12 Dexterity)
Tough (+2 HP per level)
Determination (+20 All Defenses vs Intellect, Perception, Constitution afflictions)
Confident Aim (30% of Grazes converted to Hits with proficient weapons) - offsets the low Accuracy to an extent.
Weapon Specialization (+10% damage with proficient weapons)
This is a tank that's doing lots of grazes, but they get a +15% damage bonus (from Retribution + Weapon Specialization) and 1/3 of them are converted to Hits, which also get a +15% damage bonus. I've also given him Gauntlets of Reliability - 15% of Misses converted to Grazes, to squeeze out some more damage out of him.
