We have some great things in our current reserve system, like most of the time you are on long call.

^^^^^^^^^^^^^^^^^^^^^^
Many, and I'll start with me disagree with this. I can count on one hand in my first 2.9 years how many times I wasn't on short call the first day of work. Now that I'm more senior and seeing weekends off, my short calls and FS usage has gone up because their is less open time vs weekends(I'm narrow body).

As you mentioned, transparency is gone. Yesterday I was released from short call once again, after only four hours, to be put on short call once again the next day. I asked the crew desk, "why such an early release?"
Their answer, "according to the SC matrix we needed this 0500 SC assigned." so the next day I'm given an assignment to deadhead. And now the really fun part. Once you are out of your own domicile, you are now considered a visiting reserve. Section 20 outlines this and unfortunately all legal. So now they can assign you trips from the other domicile all they want to INCLUDE HOLDING BACK OPEN TIME IN THAT DOMICILE(to give to a visiting reserve).I know this because it happened to me several weeks ago, filed a PDR, and ALPA committee member answering the PDR showed me the contract reference. So for the next 3 days I'm flying other domiciles ID's. Legal but not so much fun. And the worse part about this; It's opens time for you line holders that you never see. So for those that don't think improving reserve language can't impact line flying, think again.
