With the construction commander maybe the Development team could do coding to enable with the Construction Commander to be able to have buildings that are placed in queue's, to having the resource cost deducted as soon as they are selected. But if the player aborts building construction. Player only receive's 75% of the cost back.

This would add to the value of the Construction Commander abilities.

(This is aimed at the classic servers. As SI2 you all ready have that ability)
