TL;DR: The bow is too quiet, does too much damage, and has tactical advantages that profoundly imbalance gameplay. [Note: Having put in more hours and games with the bow, I'm reposting with edits.] ...
@nebwise I agree with everything except the sound part....it's a bow not a gun, you're not supposed to hear it. and when it comes to nerfs i would say either make the bow hit like a longbow (55 maybe 60 per body shot) or take down the fire rate, because drawing a compound bow is not child's play it is actually really draining to do so consistently.
