My experience in the last few months has been that the strategy for both the attackers and defenders has evolved. A is usually less of a stalemate, it's a tough fight, but it usually falls after a good fight.
Most people go to B since C can be destroyed and locked with a small squad and an engineer. It's harder to defend, so it goes pretty easily. C used to be the focus of much fighting, it's not anymore. Accepted defending strategy is now: f*&k C, everyone to B!
With C locked, it's all B, both attackers and defenders attempt to stuff it full of both transports and infantry. If the defenders keep their SL's alive in B, I often see the bulk of the map spent here. The hanger is won or lost for the attackers with their tank and then the last cap is often a scramble.
It's worth noting that without spawn on SL, this map is a very different experience and harder for the defenders.
