The GM:
phantom:
And for the paladin, perhaps grant a +1 stress to melee and a +1 stress to Range (vs. a +2 to either) to represent not only their prowess but their faith.
...? I don't quite understand what you're suggesting.
Since Paladins are Religious based fighters, meaning they that are not straight combat. So instead of the +2 to melee and with the update +1 to Range. I am suggesting that they get just a +1 to both Melee and Range. Because they will also get some divine powers.
I would actually take a look at D&D 4th Ed cleric / templar class' abilities and powers for inspiration. For some reason, they felt the clerics should be melee heavy. But many of their abilities would've worked better for Paladins.
The GM:
phantom:
And for the Barbarian, grant the +2 Stress to both Melee and Range, but (if we go with the Stress Pool separate from health) permanently reduce Stress by 2. Or apply a -1 to the hit rolls, because they are reckless.
I am not going with stress separate from health.
Since the Stress and Health are now the same (still not sure how I feel about that). I would give the Barbarians, +2 to Stress for both Range and Melee, but also a -1 to attacks with Range and Melee to balance it out. Perhaps even limit them to medium types of armor.
I'm not familiar with DW, so I made suggestions that make more sense to me :) and probably will continue to. Thank you for the info!
