I don't think that anyone would disagree with me when I say that the addition of the new weapons mods such as ballistics has been a wonderful new addition to the game, especially for PvP. The thing I don't understand however is why Bungie limited these mods to only newer weapons? These mods could give certain older weapons a nice boost to allow them to be competitive again. For example I was using my old waking vigil a few weeks ago and while it's stats aren't bad they certainly can't compete with the palindromes, austringers, etc. The use of a ballistics mod however could help to lower the gap. There are hundreds of old weapons that would greatly benefit from the use of these mods and I simply can't see a reason as to why they shouldn't be able to use them. I also just want to add that while I am not a game developer I don't think there is a technical reason why older weapons can't use the new mods because in the 30th anniversary event we got the confetti mod and all weapons can use that one.
