The pathing was ALWAYS horrible but the PATCHING by the developer was even worse. There were times when the community just banned certain things because they were just broken (Teuten's Town halls were only costing wood but did more damage than high costing resource units and buildings).
As a high level player a broken pathing allowed me to micro my troops and get an advantage over other players. Most players play with the speed of a 4X and there were few of us who played by trying to make 150+ commands a minute.
So this horrible pathing was seen as an advantage by faster players.
