Douple Drops.... and low drop chance

I have terrible luck when it comes to Light Side and Dark Side hard nodes during double drops. But at least I don't really have to worry about it for the Nightsisters. I already got Talia to 7 stars. I just need Old Daka from Light and Dark Side nodes, but I can get Old Daka shards from the Cantina Battles store too. I still need Acolyte though. Only have her at 2 stars. So I can farm for her shards and get a bunch of Cantina Battle tokens from Acolyte's node since you get double tokens from the node as well. So if don't get anything from Daka's hard node, I can still turn to the Cantina Battle store. My only major problem is getting Acolyte shards from her Cantina Battle node. And I get shards maybe once every 5-6 times I SIM the node. But at least there is unlimited attempts. I can go until I run out of energy and crystals, although I stop spending crystals once it cost 200 crystals for Cantina energy refresh. Plus I try to stay above 150 crystals.
