Turkish Airlines Miles & Smiles changing

Turkish Airlines just sent out an email blast about upcoming changes to their loyalty program Miles & Smiles.

Miles Spending:

Turkish Airlines is flourishing as an airline that flies to more countries of the globe than any other airline. Accordingly, the regional structure of Miles&Smiles award tickets has been revamped by taking into account geographical conditions.
With new additions being made to our fleet of planes each day, we are now allocating an increased number of seats on each flight to Capacity Controlled Award Tickets in order to improve the level of satisfaction of our esteemed members.
We are doing away with the low/high season discrepancy on Seat-Guaranteed Award Tickets. Therefore, we are providing the opportunity to accrue award tickets with the same number of Miles all year round.
From now on, by using 50 percent of the Miles required for an award ticket, you will be able to arrange the following: an award ticket in the Economy cabin for a departing flight, a Business class ticket on a return flight, a Capacity Controlled Award Ticket on a departing flight, or a Seat-Guaranteed Award Ticket on a return flight.
You will now be able to use a single table to easily arrange Capacity Controlled Award Tickets on both Turkish Airlines and Star Alliance member flights.
Passengers who enjoy traveling with a companion can obtain an Award Ticket for the accompanying passenger using only 70 percent of the required Miles, provided that the first ticket purchased qualifies to accrue additional Miles.

Earning Miles:

Dear Members: up until now, you were earning Miles based on the cabin of the ticket (i.e. Economy or Business).According to the New Miles&Smiles program, you will now earn Miles based on booking classes.
According to the New Miles&Smiles program, 600 Status Miles will be credited to your account as standard Miles regardless of distance, particularly on domestic flights. For short-distance flights, a standard minimum of 1,000 Miles will be credited to your account, as opposed to 500 miles. Additionally, you will earn less Status Miles on lower promotional classes and more on higher ones.
You can now earn Miles from promotional tickets as well.
Just like Elite and Elite Plus members, Classic Plus members will also be able earn more miles on international flights when they fly Comfort or Business Class .

Upgrade :

The New Miles&Smiles program will give you the chance to turn your travel into a wonderful experience by letting you upgrade your cabin based on a fixed number of Miles for the region, regardless of the class of the paid ticket.

Turkish Airlines has some good values in their award chart especially between Europe and 'Africa 1'. However I have failed to get a decent number of Miles & Smiles miles so far.

I'm not sure which change would do what – any seasoned members here to chime in?
