I wish that Phalanx troops had some kind of anti-cav when they're moving. It sucks when you march towards Cav and the Cav use their Nitro before you're ready - tell your Phalanx to stop, but it's too late - the Cav have already crashed through the pikes and slaughter half of your Hoplites. To have a good anti-cav with phalanx troops the Phalanx needs to be stopped AND have their shields in front of them - which takes a good 4 seconds for it to happen.
