Agree 100%. Rolling the whole Eastern front gives an impetus for the Allies to break on the Western front as the Eastern front could not be held. So, the Eastern front strategy also has it's disadvantages. But from the long term view point, the East would provide additional resources and forces to steam roll the Mid-East, Africa, India and still hold the Western front while this is going on. Due to a shorter front on the West, it can be defended. The Allies are really stretched to hold far flung positions and the Axis forces would have a shorter line of supply and ability to amass forces quickly. It would take deft planning and execution but it is doable. The West would need all of it's diplo chips to get the US in sooner as Russia and Serbia falls ideally in 1915 to get a real game going.
