Not sure if this is the right place to mention this but this lvl 8 device (Tang's Alacrity) is supposed to be a mission reward , after having done quite a long mission tree. But apparently according to one player (Patrsareus or something like that) is now dropping in Moto off high level progens , this does not seem correct.
Update .................... Kenu has had a look at the loot table and can confirm that the Alacrity is only available via the mission and NOT a random drop (.or is it ?) Thankyou Kenu
