Archer/Hunter Need help with lvl 80 boltslinger

I've been rocking this champion armour set with maelstrom/Bob's mythic bow since lvl 75.
Is there any good suggestion for level 80 boltslinger build?

 

Champion armor is perfectly good to use till lvl 100+
Once you start engaging with the Fruma quests/general harder content in the game i'd recommend you get an actual build otherwise i'd stick with champion armor for now
As far as bows go i'd stick to what you naturally find unless you feel a lack of damage

 

Something pretty simple is gale's force + void glass set from outer void. It's a late 90's build in level but should be good enough for Fruma.
