My objective is to ensure the Byzantines reconquer as little of western Anatolia as possible, which naturally means things need to go wrong for the crusaders from the start.
Since there's so much resistance to the very idea of Nicaea not falling, how much would a Seljuk victory at Dorylaeum affect future developments in Asia Minor? Suppose Bohemond of Taranto's calls for help from other crusaders are intercepted by the Turks, and thus he his troops are eventually buried in arrows.
