The GBG map is great – it shows the sector numbers, which helps very much.
It would be even more helpful if it also showed the number and type of buildings on each sector – so that you can see those without having to open every sector, then open “buildings” window on each sector.
Use case: I’m a GBG “field marshal” for my guild. I want to plan where to tell my guild to attack next. I want to know which sectors have which buildings on them.
Or another case: I’m a guild member, and my guild’s field marshal has tagged 4-5 different sectors that we can attack. How can I tell which one will be the best for me – maybe the one that is surrounded by the most seige castles?
