weaponry
long bows aswell as short bows. the long bows will be much heavier, shoot arrows faster and harder (faster as in travel, draw is slower), and require more strength to draw. compare a semi automatic rifle with a bolt action and you would know what i mean.
add crossbows. aside from bolts, the main reason is the way they are operated. a bow requires loading,drawing,aiming and then firing, whilst a crossbow is load,aim,fire- repeat. crossbows should also not change in damage much as skill increases, but rather load faster.\
throwing axes and knives with their own set of perks. i would say spears but bethesda has decided to disappoint me :sadvaultboy:
different materials should be DIFFERENT. firstly- having a bow for each material is silly. bows are made of wood, not silver.
there should be four types of wood, orcish, daedric and bonemould bows should be present. but these "style" bows should be slower to draw, require more skill to use properly but do a lot more damage and allow for a lot more enchantment. crossbows however should use metal.
ammo
Enchanting ammo.
ammo should be DIFFERENT. iron arrows might do more damage on unarmoured opponents, daedric should be very expensive and able to hold massive enchantments for one hit killing large opponents. glass,mithril and adamantite arrows might be faster to draw etc.
there should be a little classification
light arrows (hunting arrows of bonemould or iron,mithril, glass ) (hunting arrows are weaker, cheaper and lighter)
medium arrows (iron,steel or bonemould and then adamantite) (the bonemould holds more enchantment, but the steel does more damage to armour)
heavy arrows (nordic,orcish and finally daedric)
