This exactly, who cares that you won't see the trait until later in the season when by it being hidden you know it's a good dev trait? Either hide them all or hide none, the way they describe it is pointless.
Typical EA only half listening to our concerns. It wasn't that people didn't like dev traits dropping, it's that they were dropping after players had great years due to the requirements to improve/keep dev traits being based in dumb things per position.
