Building time... – Age of Empires: Castle Siege Review

I agree with other comments that it takes forever to build an upgrade. Caravan War- has a better system, you accumulate gold/gems, but once u get enough ? gems, building is easier. Castle Seige- very difficult takes forever, a player would lose interest anymore. Please consider this suggestions, make building time lesser... Thanks ?
