Arrens has another great post up on his site on The Isle of Conquest. The whole thing is worth a read, but I especially liked:
If your team is able to control the docks and the workshop or the hangar, achieving an IoC victory is a simple matter.
This is very, very true. Hold 2 of the 3 middle bases, and you can win. Hold only one, and you won’t.
(Alliance on Ruin, you paying attention? My win rate is terrible. Help a warlock out.)
