Almost certain that the Naga in the cave on noob Island would be your best bet (and just generally a good place to farm). I can't remember what town it's outside of but I'm sure one of the guys who still play could tell you.
I think sunqua blade is in the jade brotherhood/am fah drop table, so if you run dragons throat you might find a q8 one after a million chests. AFAIK the drop table between early factions and late factions main island changes, so running jade brotherhood at matuu keep won't work.
The tengu drop them too where people normally feather farm. Do that in HM with SOS or something and your bound to come across them between the drops and chests.
I haven't played for a couple years so I cannot say these things for certain, but I have a horrible knack for remembering the most useless information, and it all relates to guild wars 😂😂
