Most of the buff I was referring to had to do with healing. It looks to me like the are giving back some of the nerf sages got. Trust me I am not happy about the changes to my push back either, but I am excited the Shadows are getting a little love this time around. The people I usually run Ops with are so great that it isn't a huge deal, but I do at least like the illusion that I am pulling my own weight.
Some with better technical expertise should answer that question, but personally I do not run the repair file scan unless something is broke. I feel it is just another chance for something to mess things up. If it ain't broke don't fix it.
