The NorthThe bonus for the Northwest probably needs to be the same as Northeast and Yorkshire combined, as they are virtual mirrors of each other. Both halves require 4 terrs to be defended, so a +3 seems reasonable, although this could be dropped to a +2. The 'build your own 6' will encourage fighting between the two halves; possibly more so at +2 than +1.
The whole of the North can be defended by holding Cheshire, Derby and West Riding, for a total bonus of (currently) +8.
The SouthThames Valley is the same size as the northwest, but is totally surrounded and doesn't really offer any easy expansion opportunities. The South East and South West are fairly similar in terms of size and defendability, both containing 6 territories with three borders. The 'build your own 7' could be extended to be a 'build your own 8' without too much worry.In team games this will mean that the South can be happily shared (there are 16 terrs in the South)...
Unlike the North, there are no easy defend points, so the bonuses here should be slightly richer. On balance I'm inclined to think the area bonus should change to Any '8 territories for +2', Thames Valley is a borderline +4/+5, and I'll leave South East/West at +3 each. Middlesex will start neutral to prevent anybody dropping the Thames Valley bonus
The MidlandsI envisage that the middle of the country will be a bit like Asia on Classic, in that any battle for it will take place later in the game. The regions are slightly larger than elsewhere on the map, and will possibly be chipped at from both sides once they are held (depending on the drop). With that in mind, I think the bonuses should be slightly higher than currently, with a much smaller +1 for holding any 4, for example... I wonder if that would actually encourage people to build in the middle, and then expand into a region; without being an overwhelming advantage on the drop...
So, the Midlands could change to: Every 4 territories +1; West Midlands +3; East Midlands+4; East Anglia +6
Thoughts on this?
