I really like how fluent the ranged attack feels for the pirate class, continuing your movement and being able to jump, dash. I would love to see house rule options to apply to other classes and spells.
Archer is mostly what I'm thinking of but you could also probably do some crazy stuff with the gunslinger... But I'm also taking about spells, I think it would be really fun!
Of course it would be a house rules option so not every player has to do with the flow that the ranged pirate attack has.
