Balance the World Border Corners

This may be more of a suggestion for next season (not sure what the current status of the corners is, though I know they aren't fully balanced) The world border corners are the most valuable land in the map, as you only have to build defenses on 2 sides (rather than 3 sides for a border edge base, or 4 sides for a non-border base). You also need less power to claim the same number of chunks of defenses. For this reason, the civ biomes in the corners of the map are something to take into consideration. Currently, it's possible for a civilization to have multiple corners, or NO corners. You can go to a corner of the map, then choose your civ, but I'm still not sure I like the possibility of one civ having an inherent advantage before SOTW even begins. I see 3 options 1. 1 corner for each civ + 1 neutral corner 2. 4 neutral corners 3. disable corner and possibly border claims (not as much of a fan of this) IMPORTANT INFO BELOW
