It still works the same.
No more milkrunning.

It may still work the same, but all of the strats are in one place where before they were spread out. It's too easy now to defend the strats because of their location, and there is little effect on the game if you do indeed wipe them out.
There was zero reason to change from the zone strat system, but it happened anyway. quite sad really for those who liked to bomb stuff...
Oh, and wrongway, you can still milk run, you just have to hit town centers from 30K feet which of course sends the town out of sync for the base taker crowd. Nothing like messing with your country mates...
