I also don't see a problem with the available space. We have 48²=2304 fields available and generously calculated (with 3 event buildings of 5², roads not under traps or gates, no buildings in the bastions) we can only occupy 1669 fields. That means that almost a quarter of the available space is still free. With even more space, the time-waster base layout will only get bigger.
I don't see any added value in putting the Armory or War Academy on the sidelines. It is your free decision to choose a place for it. You can place the buildings on the edge yourself, then you can find them just as quickly.
If we're talking about fundamental changes to the map, then I'd rather see an animal park next to the alliance gate, so that the animals, oil leaks and drops are concentrated in one place again, as it used to be with the forest. And I would like to see the solid forest on the bottom left edge trimmed a bit. Because on the outermost row, behind the tall trees, sometimes small structures (oil leaks, piles of gold from caravans, chests/rocks after clearing) are hidden out of sight . And I would like to see airplane paths calculated uniformly across the map instead of making confused loops on the two left edges.
