critical/kill animations for mages and archers would be awesome. So would the perk to fire two arrows at once. Reduced accuracy and more damage for close range. Perhaps a robin hood perk where you get option in vats to make the next arrow hit in the exact same spot as the previous arrow. Maybe an arcane archer perk where you can use your MP to infuse the current arrow with fire,ice, or electricity. The longer you hold the arrow back the more charge it gets until it uses up all your mp for an aoe shot that freezes, shocks, or burns a certain range of enemies around the target on impact. The more charge, the wider the area of effect.
