It didn't, really, as most of us never lost anything expensive. The only ones who drained their money were the two engineers, but we donated here and there. I just thought the ore trucks were worth mentioning. Our defence was pretty solid, we even had a sniper in a valuable position telling us when to expect rushes, what type of rushes, and where they would most likely be coming from.
Regarding everything else, I'm no base layout/map design expert so I really can't comment. However you could've tried getting a spy into the power plant to disable our power before attacking the coil. That's one thing I told my team to expect but as far as I know was never was attempted. You could've had a Tanya + engineer use a chinook to attack the power plant while the longbows attacked the refinery. Maybe tried having Totd get out of the cannon and into the artillery to bomb the base of the coil to harass engineers and technicians while the tanks attacked the coil? I don't know if any of that would've worked but it would have been something different. The only rushes the Allies attempted were chinook, longbows, or tanks with the cannon shooting our base.
