I just opened exactly 100 ultra boxes (so 300 rare/legendary cards), plus hundreds of random boxes, and even some engine boxes, and have now opened 3 of the basic R&D boxes, and still have not received even one single legendary electric engine.

Is anyone receiving enough of these engines from just the R&D rewards for 5050 PRO, without having to spend tokens?
