Maybe, my shard is an anomaly then, I don't know... I think I started using JE at 5 or 6*, but it did take a very long time to farm him since Guild shipments was the only way to do so. I started farming him after I completed Rey, which was a mistake on my part, though Rey was very helpful with my team with no synergy, and in doing a lot of damage in the Rancor raid. I decided rather late to run droids. I don't remember what everyone was using before level 69 then though I don't recall seeing more than 1 or 2 droid teams. I know IOS users got Wedge for free at one point.
