Kwejsi is fine the way it is and I personally feel like it's a well balanced map. Just because CT's are now accustomed to the map secrets doesn't mean we should revert or add new map secrets into the mix. Rebelling opportunities honestly should be well thought-out and risky. If the CT's know there's an easy secret to get to, you should ask yourself if you should risk dying to do it.
-1 for this suggestion.
