Truth be told, since RNG is a cruel loot mechanic, I have to make do with what I find or unlock (like the Shrillbuster).
I end up deleting most of it anyway, because it's all weapons I don't use.
The primary reason for using it was that I was sick of firing a VOT LMG at point blank range and killing myself with the backblast!

And I think it would be extremely foolish to start buying dozens of boxes with real world money just to get an OJ or the Shrilltech assault rifle.

I prefer guaranteed rewards, earn enough of currency X, go to vendor, buy item.
I did inspect the Loyalty vendor and there is some orange gear I want to use, including two shields with 100% health regen (haven't decided which one I want yet).
But we're talking 1000 Loyalty points for both the shield and one weapon. I am uncertain if that target can be achieved.
I've got 17 currently and it's all going to be spent on an Epidemic lockbox that will most likely give me all non-Shrillbuster compatible mods, like shotguns, detonators, infectors, etc.

I'm hoping that I can trade a useless mod for the one I do want.
But it depends on if an epidemic mod is generically useful or only the ones compatible with assault rifles.
