Well for starters, it's a suggestion something for other players to look at and consider as an idea.
My suggestion wasn't for swords and spears to be the same more so as alternatives to each other offering differences. Most games offer a variety of weapons with slightly different play styles for players to pick from; bows and spears as you say might be the most widely used tools, however I can also count the number of games I've played that have spears in them on one hand. As for arrows in the current state could they not be changed to better their performance? Again I haven't used a bow in game but if they drop as fast as you say sounds like something that should change. But I get it you don't like my idea but this is also a suggestion for the suggestion forum.
