bowazon using all type of special effects, such as slow, knockback, curses, openwounds, flee...
You need strafe or multi shot to get the effects to the monsters fast enough, if you want, you can kill them with a javelin afterwards.
If you are ladder and you want a cheap good bow, you have two options: make a wws strafer and know that you can't change to faith or wf (no critical) if you ever find one.
Or use harmony and know that every bow (besides wws) is a bow you can use in the future. Just be a bit carefull with penetrate and you can even make a near perfect faith azon.
P.S. or you can just make a wws strafe azon and keep some spare points for critical if you want.
