FAR too many ''good'' options.. there's a line between red herrings and just random chance, and that's on the wrong side of it.

I respectfully disagree- it was by no means easy but entirely fair- the 2 good groups were distinguishable and not interchangeable, the other "good" prefixed words- which honestly could be almost any word, stood as viable red herrings. Usually too many in a group is irksome but I can see that here it has been used as a motif and unique style. I had no problem with it, just makes you think a bit further beyond the obvious. Not popular but not necessarily bad.
