First of all, I have to say this version is beautiful, the depot, convoy and train, concept is beautiful, WTG HTC!

But...
The actual strat system need more cooperation (first kill city, then stations, then factoryes), but even in the case a nation (knights, rooks... no, not bishops, they are not capable of

) can organize massive raids to impair the enemy economy, this is useless at the actual recover times, while the strike force go back home, the structures are fully operational again.
Imho the rebuild time of structures need to be pumped up (say 1h or more standard recover time), with only the resupply and convoys able to shorten the rebuild.
Or, much better, only convoys and resupply will rebuild stuff.
What do you think?
