People complaining about the rogue changes are really surprising to me to be honest. The Dark Zone was way too much of a care free farm excursion for the last two weeks. In all honesty, I think it gave people some bad habits. I run the Dark Zone a lot solo (and have been in there for a couple of hours today solo), and there's really some common sense things that a solo player needs to be aware of...
Number one, regardless of anything else, you are at a disadvantage at extractions. Yes, the people who just rolled up on your extraction may be the nicest people in the world, but if you are solo, and someone comes up during your extraction its probably time to hang back and be ready to make a break for it.
Number two, always be aware of your surroundings. With a group, this isn't as big of a deal because you can easily offset any errors in awareness with sheer fire power. As a solo player in the DZ, you don't have this luxury. Any number of players can be a danger to you, and as a result if you are trying to farm solo, treat white blips from other players from your pulse (which you are using, right?), as a much higher level threat and try to avoid if possible.
With all of that said, even with the time that I was in there today, I haven't witnessed the ganking out extractions that people have been complaining about. I think it is mostly because of the above two things and the fact that I try to avoid extremely popular extraction zones. The changes finally brought the DZ more in line to what I think the intent was, and that is a dangerous place to go to get geared up where you have to fear both enemies and players.
To me, this is the way it should be.
