The thing is, I believe that the show exaggerates what is happening. A character says something to another character, and it is "confrontation" or "attack". This is hype talk to make us excited, or eager to see what transpires. When it falls flat, and the viewing public wonders "is that all, that was nothing", the suits don't seem to get it thru their heads that the public is not going to believe anything they read any more.
I do not think anything filmed months ago has been re-edited. I think the editing has always been poor, still is, and that filming 1 1/2 shows per day gives them room to cut and paste scenes from 2-3 days of filming, making a mish mash of some shows. The intent is to pretend they really are an "ensemble" and there are more than a couple of actors hogging the airtime.
Thus, lots of meaningless filler, filler, filler at times.
