I think the rune preservation based on the level requirement of the staff is very unnecessary, barely communicated and a huge effect on the runecrafting market. I'm more inclined to plea for removal than even increasing this preservation, giving the elemental staff a little more use since it preserves all elemental runes.
Same for the proposed solution to remove ammo for elemental bows, but since ammo preservation is already a thing because of ava, i'm less against this.
God bow range nerf agreed, and then elemental bow indirectly receives a buff. Increasing the accuracy to match dps with the stronger ammo for godbows is also a potential (additional) solution.
