Armorer desynth

I have read the desynth thread on here with what to use for skill ups and such but I am stuck at a hurdle. I am 75 desynth on my armorer and with pvp ques being terrible usually over and hour does anyone have a suggestion for how to get better skill ups? I am currently getting .05s roughly from aged mortors which isn't really beneficial and have been trying to farm dark light/protectors armor from brayflox hard only to be outrolled. Without crafting my own DS armor is there a cheaper alternative?

Considering the cost, if you are getting 0.01's from the Aged item you still want to be desynthing that.

I did dungeon gear. Things do slow down a lot in the higher levels when you can no longer just buy piles and piles of cheap stuff to speed through. I would say just do a whole lot of dungeons, hope to not be outrolled, and you get somewhere eventually. At some point I just stopped thinking about it and let it happen naturally over a long period of time, now my armorer desynth skill is at 105.
