Why are the lower level augments so hard to come by? I realize that some of this is driven by the fact that people are only at level 1-15 for a short period of time whereas they reach level 50 and stay there; which would tend to drive the prices of lower level augments higher by virtue of supply and demand. But I would think that people still need to grind slicing up and need to run missions in order to help drive that process.
I still think it's odd that I haven't got a single drop though. It's also my second character, and I've purchased all three "crit" legacy bonuses. To have had so many missions not crit at all seems to defy the laws of probability.
I suspect it is a combination of a couple things. One, some slicers may not run missions for the first few levels, leveling slicing by the slicing nodes out in the wild on the starter planets as they level their toon. Also, you blow through those early levels pretty fast, few people get enough of the lower level schematics to bother selling after they give them to guild mates or send them to alts for crafting.
Where as with the highest levels, people run those missions much more frequently for the mats...and the 22's are, as previously mentioned, not worth much at all.
