Hello, this may be a n00b question, but I am mighty confused about this.

Is it helpful at all to help build forts and castles with multiple commanders? Does the building army contributes to the speed of construction? Common sense would indicate that a large army with multiple commanders should build significantly faster, while a lonely scrawny priest would need an eternity for the same task.

So does the number of "builders" matter, or is build time just fixed regardless on who is doing the work?
