I was told to share this hypothesis with this forum due to the great skills members have here. You'll see why that is relevant soon. But first, an early apology in case this is not the correct place for this post.
So Spyke has never given me any gear that had subabilities unlocked, as far as I can recall. I've seen on these boards from cursory googling to try to figure out these mechanics (and I have yet to see a definitive answer, so I apologize if this is all sorted out by now) that it is indeed possible to get unlocked subabilities on the gear Spyke sells. The people who this happens to insist it's pretty normal and others must be suffering terrible RNG to rarely get the unlocked gear.
I believe there has to be something more than terrible RNG to this. Dozens of Spyke orders, but none came with anything unlocked, until today.
I had hypothesized that a Hot Streak is necessary for the upgraded gear. My routine had usually been log in after midnight, check the shops for new gear, and get the order from Spyke. As you probably notice, one thing would be common in that routine - I'd have a hot streak of 0 at that point.
So today, I changed my pattern. I worked to get a +7.0 Hot Streak. Then I talked to Spyke. Lo and Behold, I get the fabled message that he has found gear exactly as I wanted!
It was a 1 star gear, with the initial order having all three slots, but only the first slot was rolled. Spyke offered me a single slot, that was pre-rolled. I've seen posts on here suggesting that you can buy gear that has more slots than stars, but I haven't had that luck thus far. (Might on August 5th.)
Anyhow, my reason for posting was to see if anybody else might think this hypothesis plausible, if they've tested it themselves in the past, or if they'd be willing to test it out and report back results.
