I still love my FC. I've got a GREAT base layout in Global Age now and getting quite a lot of defence wins. In fact, I've been mostly climbing the league on the back of my defensive wins haha. It's an open style base but the beauty is that the FC is exposed and leads an attacking army straight to my heavily trapped TC. The FC is also 'guarded' by 2 factories which will immediately spawn heavy tanks. so when the enemy deploys troops there, they immediately have a couple of HT's to deal with which stalls their attack. It's awesome. Wish I could share a screenshot but don't want to give away my competitive edge in our wars.
