1.
Top 8 finishers get points
Not necessary in my opinion. The point distribution wasn't really a problem. And currently the number of cars gets less and less, soon everybody will get points.
2.
Two qualifying sessions, one on Friday and one on Saturday
Wasn't the Friday qualifying abolished some years ago, and rightfully so? Who is able to watch that at about noon on Friday (considering the European races)?
Furthermore the cars will only have
one flying lap each per qualifying session and they will all drive seperatly.
Although there's something good about it I think that it emphasizes luck too much (just think about rain setting in but also smaller weather changes like temperature).
3.
Less testing
I'm okay with that, but I don't think it will archieve much.
4.
Each team will be allowed to use two different dry tyres at each Event
Hard to tell if that will really be of benefit for smaller teams, as officially intended.
5.
Team orders banned
As mordhiem said, how are they going to police that?
6.
Belgian Grand Prix removed from the schudule

A really bad decision. Spa is in my opinion the best F1 track because it demands at least a bit from the driver and not just the car.
All in all I think it's a very bad decision. Almost all changes are not necessary or even dangerous for a competition in the sense of sport (the qualifying for example). And the real problems, for example that overtaking is almost impossible on many tracks, have not been adressed. The electronics have not been reduced, why didn't they just abolish the drivers?
