The other day in Kerrat, I was fighting a tactical cube and a group of probes. After I was one shotted by a plasma torpedo, I went back through the logs to see how much damage it dealt (something like 40k I think) and I came across this:
[CombatSelf] Your Chaotic Particle Stream deals 1000 damage to Probe.
This is exactly what the [Borg] proc on the old STF store weapons does. While I have only seen it once (I still have three Borg turrets on my ship), which was this instance here, it is apparently not entirely gone. Just thought I'd share this.
I am the STO Lorax. I picked myself up and left, until the day the fun is replanted.
