I suggest series of measure's to 'take down' Aegypt expansion - like, weak the start position of the Aegypt army by adding more unit's to Seleucid's wich will make them force Aegypt to defend at the start and that should prolong the AS life.. In any case - AS are loosing over to the Aegypt in any case

Second, I really think that Makedonia is uderpowered - read the report up..
So they should never loose Corintos that fast and Pella should have Stone Wall because of the Pyrros elephant (wich is very usefull if you play Epeiros)

Also, the testing's are clear about the massive use of royal and army barrack's by the AI - that should be 'resource' limited to 30% of the region's so Aegypt wont gain mad pace after 240bc when all Seleucid's town's already have Army barrack's (due to the share system). If we make 'resource' limit's it will further make AS postition stronger and therefore more less likely to loose at the start
