I ended up making quite a few changes....
The ruin next to dragonstone is now just a random lvl 3 (no more free dragon
).
The ferry near Harrenhal now has some forest and hill options to prevent HL ferrymen charging too high a toll
I did a bit of tweaking to improve the ironborn, lannister and baratheon starting positions.
Sunspear is no longer adjacent to water (delaying a possible Dorish naval attack on baratheon).
a road in Dorne has fallen into disrepair (slowing down dornish expansion).
The positions of some southern cities have been adjusted slightly to encourage more early conflict in the south.
The kingswood brotherhood have returned and are waylaying travellers on the kingswood road between kings landing and storms end.
