Gear Bottleneck.

To me the worst part is raid gear. I think I've only once got a fully crafted gear piece, and most of the times I get more challenge gear, which I already have thousands of. I would like these pieces to be farmable, instead of relying on RNG generated rewards. I have at least 5 toons which I'm currently interested in gearing for TWs, and none of which I can do anything about because they all require raid gear, which is impossible to farm. I've had more trouble gearing past g9 and 10 than I have taking some toons to G12, where most of the gear is in stores and you just need a little patience to get. If I at least got some raid gear for sure every raid this wouldn't even be this big of an issue, but sometimes it can be months until I get a single drop of the gear I'm looking for, while getting challenge gear, and most of the times you need a couple drops to get enough to fully craft the gear you need. A couple of examples would be the Mk5 Arakyd Droid Caller or Mk6 Nubian Design Tech. Yes, I know they sometimes pop up on stores but not at a reliable rate, and even then it requires you to spend resources that sometimes you already spent on something else you are reliably farming from that store.
What I would like to see is these pieces appearing somewhere reliably, even if the drop rates aren't the best, so I at least feel like I'm making some progress. Otherwise it's just frustrating having some characters just sitting there, waiting.
