FIRE arrows normal damage is very low, fire its much better but fire damage dont stack, so its beter to one of you shot fire arrows and other one flint arrows or even wood ones.. you must wait for fire to burn out then shot another...playing like that you will shot 30-40 an he will shot out about 50-60 arrows...

i'm pretty sure fire damage now stacks. so you don;t need to wait anymore. just shot-shot-shoot
