When the other side opposing you out numbers the defenders 3-1, sure it's easy to roll things up.
Last night at A18, due to the low Bishop numbers we could only muster 2-3 defend a base being attacked by 15+. Sure, those 15 got a lot of kills, it would be hard not to when you can put 3-4 guys on every defender. Come to think of it though, the 2-3 defenders at A18 did manage to hold onto the base despite the overwhelming odds stacked against them. Hmmm...mighty Rookies...
