As the title suggests I believe that Archery could be further expanded upon in the combat system.
Right now Archery is kind of lackluster and is not even a viable option in PvP or even PvE for that matter as there are better options in melee combat. With the current hunting meta being Boar spear on a boat with Quick barrage and Full circle, occasionally with opportunity knocks, it's generally the go to for mid to late game hunting while archery is an option that's just it...an option. As for PvP it's not even viable as player can just sidestep incoming Arrows with their lightening fast reflexes and rush the archer to unleash a can of whoop ass.
I feel a potential solution to this is adding new bow and arrow types that do various thing E.G an arrow that can bounce across water (such an arrow actually has been historically use by the ancient Finns) or arrows more oriented to piecing armor or inflicting openings for support via combat moves in the form of "Shots" E.G "Curve Shot" to hit around corners or hit moving targets (like how throwing axes currently work).
just putting out some thoughts I truly believe Archery can be just as good as melee combat.
