This isn't about NM chests. It is about UNM, and it isn't about the type or amount of drops, it is about the quality...I get a shard or book or shard and book from every transcendent chest. The issue is the shards and books have been ONLY ancient and epic for well over a month.
Statistically it has been unlikely, but not impossible...even with it affecting about a third of my clan. Sadly, still not out of the realm of possible. At this point I'm just curious how long someone has to draw crap rewards before plarium realizes that getting the worst rewards for that long is an issue. Luckily, I've spent enough in the two odd years of playing that I don't "NEED" any champions to complete content, I just enjoy the dopemine hit I get from pulling gold...but this streak has broken my addiction and i've lost the desire to hand them money to get my fix.
Thanks for forcing me into rehab,
