I have 13 toons, Lokin is one of the easiest to get. 4 toons are into bioanalysis, when they went to recruit Talos on Yavin, plus doing the weekly, they gathered enough mats for Lokin. When a character not into bioanalysis needed the mat, another went for the Yavin weekly. I devoted an entire section in my legacy storage for materials, mostly for crafting.
All in all, it takes way less time to get Gyzen plus Lokin than it takes to get Pierce/MX
