With the release of various documents, we tend to be quite vocal and we provide feedback for everything we see. After years of playing, we can instantly spot something that we know won't work.
However, our feedback is biased towards the mechanics that are in place today, and not the changes that might happen in the future. This is because we don't know those changes.
So, if there are plans about how ACs, specials, perks, damage, defenses, HD, ND, etc might work in the future, us knowing about those plans might help in maintaining the discussion to the point and provide a much more accurate feedback.
Food for thought.
