one solution:What version of exploding dice?
The one I've seen is that if you roll max on any damage die, you roll again and repeat. My barbarian with a two-handed sword (2d6 damage) and savage attacker (reroll <edit stupid autocomplete> damage 1/round and use either one) would love it. That paladin with a great axe (1d12) would only see a minor improvement.
rework all damage dice to d6
One handed weapons: 2d6
2Handed weapons: 3d6
light weapons: 1d6
additional weapon traits can increase or decrease damage by point or two.
IE: Heavy weapon: +1 damage
martial weapon: +1 damage
finesse weapon: -1 damage
thrown weapon(40/120): -1 damage
2H reach weapon: -2 damage
1H reach weapon: -3 damage
ranged weapon(80/320): -2 damage
ranged weapon(150/600): -3 damage
Loading weapon: +1 damage
Loading weapon(bonus action): +2 damage
Loading weapons(Action): +3 damage
with only d6's, every damage die has 16,67% chance to "explode".
