Pretty straight forward farming the emblems, it’s actually quite quick as well, depending on how proficient you/ your party is at combat.
I think i got my uniform in less than half an hour soloing.
Anyways, on to the farming, you got it half right.
You indeed put on your talus dominion uniform and then you defeat the skyheaven resistance npcs inside the skyheaven bastion area (in the southern portion of the misty woods zone).
Now thing is, they don’t drop the insignia, Junghando does.
That’s right, after a few skyheaven resistance member kills with BNS Gold, junghando and two members of the red guard spawn in the zone, either by the barricades in the north or bellow the slope in the south of the zone, basically in the combat zone where all the npcs are fighting each other.
It’s very easy to miss him if you’re not paying attention and if left unaggro’d they will simply leave, so keep an eye out for them, they really don’t stay around for long unless you engage them.
He’s easier than when you meet him in the tower but he’s got backup, not to mention all the npcs around the zone.
Hope this little guide helps you & other people looking to farm their skyheaven resistance uniform ~
