Reload movement(you can't move while loading)and bow needing to be fully loaded to shoot are it's only weaknesses. Otherwise, it deals 3/4 hp like b3 and has a good melee switch speed.
b4 are good in a “I’m against pro sniper” situation since the speed it gives you and poosting, but b3 is easier if someone is any other bow besides b4, but I will agree that b6 is better
