I see a lot of complaints about the PvP meta, balance changes, etc. However I see few solutions being offered. I present to you a solution that fixes many agendas.
Bungie's side: we want balanced weapons and more primary gun play.
Player's side: we want to use whatever weapon we have, feel competitive during use and the ammo to use it.
Solution:
All weapons are useable. Players spawn with standard primary ammo, 15 rounds of special and 2 rounds of rocket and equivalent amounts for other heavy types.
Ammo no longer spawns on the map. You run out of special ammo you have to get a kill with a primary (every primary kill returns 1 round of special), run out of heavy you have to get 2 kills with a secondary (2 secondary kills returns one round of heavy).
This approach starts everyone on an even playing field, gives players choice in play style, reduces if not eliminates the advantages of camping or passive play style and promotes a diversity in weapons used.
Thoughts welcomed!
TL:DR - PvP Juggler Modifier (minus primary ammo).
