I don't think it's "shady." CG said the odds weren't even among all rolls. And you can see all the options that you might get. And anyone who has been active in the gaming world over the past decade should know that they aren't skewed in our favor.
I do, however, think it's a bit scummy that we don't know what those odds are and the gaps between the best and worst abilities is such that many of them just aren't worth having at all. Never feels good to spend resources and feel like you got nothing useful out of it. Guess who rolled TFP on their first set 4 DC!
