But how many of us have really been that unlucky?
I started a new toon aftr season 6, my current main, and got pretty consistent trops of proto tech on all 6 STFs.
I stopped keeping track after I completed all sets on my 104th run. But on average that gave me a drop every dozen or so STF evenly spread out between the different missions.
I know, it's not a very big sample size, but it seems too even to be THAT random.
