Well . . . the first three chapters are free to play so if you try it out, you haven't lost any money. If you are considering playing it, you may as well go through my link and help get me some SWTOR referral points! http://www.swtor.com/r/Yt4Qdw
No everybody isn't moving away from SWTOR. It's not dead or dying. It's still quite alive. As SH said, The first chapters are free, so give it a go. I'd give my referral link, but you can only use one at a time.
By the way, I just remembered this perfect video that answers your question. "Is SWTOR worth trying in 2019?"
The item has no properties, it has a required feat that Mira has: "Weapon proficiency: Wrist Mounted Rockets".
I haven't tested it but you can give that feat to your player character with the KotOR Savegame Editor.
