Personal sugggestion

the current race advantage is not yet that noticable nore accuracte. plus additional more races is possible, (pls, add the salamanders in the ultramarines color)
more units. the currents units are a bit too fplain and the unit balance is not that balance yet. its all about quantity and the balalnce will not be no possible comeback for theunderdogs.
resource production in the taken cities are a bit proben as well. no reduction causing masive production of resources.(given orcs a big advantages in the early days)
-unit balance and must be balance and counter units must be counter units.

possible addition more acuracte units as well. and balancing as acceptance as long as its as close as the lore is. (possible titan production is you may but of course you can balance it as well)
-and a genuine question.do you want this game just as call of war 1914 (quantity and industry driven) or call of war supremacy(match up and tactica and stratregy driven)?
