I think you've played with different croc then I did.
Mine took ages to vet to get range increase and wasn't even close to 60 range.
Also, melted to 2 stugs in seconds.
I have no idea about this, but I remember playing Warlord Battlecry III with friends on LAN and sometimes there was sync error and result was excatly the same.
I was thinking I'm crushing my friends but on the hand, they were crushing me on their screens.
In my opinion, biggest problem about USF is how much micro they require.
RE, 3 RM, Lt, 50Cal, Cpt, Howie, 2 AT Guns, Ambulance and you already have 11 units to manage which are very easy to kill.
