@rockyboy1998 I think they are worth it but they have to be used with the right legends.
The gold back pack goes to either the LL or Mirage on the time. I also give who ever has the gold back pack the gold knock down shield. Simply because if they manage to pull off the self revive, they'll have health. It is rare to successfully pull it off, but when it happens it can be awesome.
The Gold Helmet I tend to give to what ever legend has the longest times on their tactical and ult. If all legends are equal then i tend to give it to what ever legends abilities will be used the most and have the largest impact for the entire team.
The gold armor is decent. I tend to give my teammates my batteries and only carry cells/syringes when I have one. That can help the entire team out especially when heals are in short supply. I have also found popping a cell mid fight, especially in close fights can be a deciding factor in who wins.
The gold armor also works great with the Sentinel, you only use 1 cell to charge it instead of two.
It's really about priority. Those gold items won't win a fight for you entirely, but they can be just enough to shift a close fight into your teams favor.
The gold guns I love. I don't have to spend time looting attachments. They are super OP on drop as well. You have a fully kitted gun on drop, while your enemies have no or few attachments. It's a huge advantage on drop.
