Please convince me that this is random

I've been farming my Ewoks since the C3P0 event was active the first time. Still haven't been able to get Logray to 7*. I check every single store refresh; Logray has not appeared in my guild store even one time since about two weeks before the event's return was announced. Now there's nothing but a $70 bundle to get guaranteed shards. I need about $4 worth of that pack. Someone please convince me that this is actually random, and not EA/CG attempting their traditional cash grab.
