That's what I have been saying all along, after looking at the save I would say that pretty much every city should build a barracks and then HAs. The barbs will spawn in twos, so we should've 4-5 HAs in Samarqand, 2 in Marv and 2 in Mazar. Gwadar can sent troops to take Zaranj (Cata, Sword and HA will probably do) and complete the Greed. Meanwhile our workers should connect Mazar-e Sharif to Herat, Herat to Zaranj and finally Zaranj to Gwadar. This has already been started and we have so many workers and pretty much everything improved that we can easily achieve that before the Seljuks spawn.
