My issue with adding magic quivers to D2 is that frankly Bowazon have been just fine, and were even before the 2.4 buffs. They don’t need any more power. They still massively out perform every melee.
The issue is that a few builds Blizz/Light sorcs, Hammer/Foh Pallys, and Javazons are just way too powerful as Blizzard didn’t account for the extra +13 or more skills everyone runs around with these days when they calculated synergies back in 1.10.
The added mods could be slight like +5% more life or +250-+500 cold damage or +15% elemental damage. Maybe a magicaly enhanced quiver has faster arrows but at 25% less physical damage, or heavy arrows but increases physical damage by +25%.
