[SGA] How to game Juggler to get Heavy ammo?

Heavy ammo synth is overpriced, so what's a poor Guardian to do when faced with Juggler? 1) Shoot rocket at mob from distance 2) Switch to primary immediately before rocket hits 3) Watch it rain purple ammo (or be smited by the RNGod of Ammo) This will trigger a drop for either your special or heavy because you have your primary in your hand. I do this with Ruin Wings equipped to add even more drops. Relevant source: [url=http://www.reddit.com/r/DestinyTheGame/comments/2rf9oi/sga_when_juggler_is_on_fire_a_rocket_then_switch/]link[/url]
