Put Rey back to Guild Store, pls

I was going through something similar. I finally got her to 7-star, but it took forever. It seems the game "knows" what you are doing. Rey wouldn't pop up for a week or two for me in the Guild Store. Now that I'm done farming her shards, on an average, she pops up at least once a day. Sometimes she'll be there 2-3 a day or every other refresh. Where in the blazes was this drop rate when I was trying to get her shards? Something is up with the game. Now I'm going through something similar with Darth Maul and Wedge. Those two were constantly popping up in the Guild Store and Fleet Store (well, just Fleet Store for Wedge) when I wasn't trying to farm them. Now that I'm farming them, I get other characters I've finished farming shards for in their spots. Well, in the Fleet Store. Where Darth Maul pops up in the Guild Store, I get other characters I can farm elsewhere. I could farm Wedge from Cantina node, but I can't 3-star the node and just use sim tickets. Plus I'm trying to 7-star Lando from Cantina nodes.
