Changes to Gold Equipment + more Gold items

I think it's safe to say that the gold backpack is the best item in the game, making the other gold's look pretty weak in comparison. These ideas could make them all great.

Gold Armor

I propose a the wearer gets 25 shields back upon downing an enemy/killing a downed enemy and still keep the refill shields upon executions. 

Gold Helmet

Same effect just make the cool down buff the same percentage as the bag (50% I think/not sure)

Gold Knockdown

Self revive should be as fast as Lifeline revive + can use gold shield and turn while reviving self

Gold Light and Heavy mags

Same capacity as purple mags but with a 10 - 25% reload speed increase.
