Host required for weapon mods?

[DuskLight]

Just created a simple weapon mod to increase damage from the harrier assault rifle from 106.2 to 900.

I soloed a gold lvl match, and was killing enemies pretty fast, but of course I was the host.
I then got into a silver lvl match where I wasn't host, and it just felt like the damaged had dropped down significantly.

So as the title suggests, do I need to be the host when utilizing my weapon mod?

Yes. The host is the one who does all of the game calculations.
