4G bandwidth QOS issues with new FW 6.1.2

So is any of this going to be addressed in the next firmware release? Because it seems with each new FW after 6.1.0 new problems keep snowballing making the new releases unusable for me and it seems many others as well. Personally, if I could get a copy of the 6.1.0 firmware installed WITH ONLY THE AP ACL ISSUE FIXED - every thing else left alone - that would solve all my problems. Is that a possibility maybe ???
