This game has such a horrible interface, in so many ways. It really needs some in-game or online help files explaining it.
Apparently a crate I find isn't a "thing" I open, that contains "things" I want (gear). It's a "token" that lets you buy a Premium Pack for free. WTF?
And the whole "Scavenge" term is pretty ridiculous too. I'm not scavenging anything. I'm not going to a random battlefield and finding stuff for free. I'm paying a virtual store to get random collections of stuff. As much as I want/can afford, anytime I want. No relation to battles I'm at or have been to.
I had to Google around a good bit to find out the whole "token" bit. I can see many others are confused too.
This is just about the worst design imaginable, in concept, terminology, and UI.
