To be honest, while map itself is nicely arranged and probably accurate in terms of names, connections etc., this, as other maps that try to resemble actual situation in one period of time, suffers from the same problems.
I myself moderated online game regarding WW 1 about 15 years ago, and noted that you cannot balance things by adding more lands or having more players if only one part of the map or few players are considered as decisive factors for the game.
Here I see waste plains of Russian Empire and just by checking their income you can see that sole player having that position can obliterate map in few turns (literally). Other two positions strong beyond reasonable points are India and Ottomans. Having India and Russia on the same side (and they are allied) will do things behave far different that authors idea.
Warlight doesn't offer trenches or fortresses as part of the game (maybe in future?), so it is not easy to predict what the course of the play would be, but I don't see how German Empire or Austria-Hungary can pass own border. To reflect trench warfare, attack value should not exceed 0.35 and defense value should be at about 0.85 - having standard values both Germany and Austria-Hungary will be eliminated in turn 10, this way it may be postponed to turn 15.
What I want to say is that you should consider posting some elements of the bonuses on vulnerable positions or lower all bonuses to reasonable level - to reflect that main theatre was in Europe.
Vulnerable positions for bonuses could be (for example)- Port Said or Suez (loss of either of these, while holding London would be -50), Sevastopol (loss of Sevastopol while holding Moscow would be -100), Kongigsberg (loss of Kongigsberg while holding Berlin would be -50) etc.
The key how to do that you may find in
https://www.warlight.net/Map/15987-Issanders-New-Strategic-System-Africa - while it is not helpfull itself for this map, it can give you clue how to post strategic elements in your map.
Other thing is that looking for accurate levels in colonies will actually clog main theatre - you will want having more players in Europe, but you gave them only few valuable positions.
