Will I get experience/loot for playing private story matches?

My first and only private story match just ended and it seemed like it glitched saying “cannot retrieve prior match information” or something… So I can’t tell

Yes, you will.

And some of the best gear drops in story. If you are looking for a particular piece of gear, you can just farm solo if you have a character you are very fast with (I can do algorithm in 24 min with Toby).

You can definitely farm the story.
The game’s a GBX game!!
Farminglands ahoy!

That’s tragic. But certainly an unintended bug. I’ve played about 15 hours so far, almost all of it single-player story and I’ve been collecting excellent loot. I was thrilled to see legendary items.
