You may not be aware that the droid that spawns near the pylon of the PvP area will also spawn in the southern section of the Western Ice Cliff. This image created by Clopsy of Jeddit will show you exactly where to find it, including coordinates. This is a great find since it makes it easier to catch the spawn.
There are eight confirmed spawn locations here and the spawn rate is 7 minutes.
Check out the graphic to see for yourself.
Thank you Clopsy!
