I understand that. I'm rather spread out all on my own with some villages 2 hours by cav away from my main. I'm converting two of my villages over to just produce defensive troops. Nothing else. That way I'll have a ready supply of soldiers to send to those who need it. My goal is to have 500 preatorians for protection in each of those two villages and everything else will be to send off.
I think we need a strategy though, not an indivudial one but a alliance wide one. I would sugest that everyone with three villages devote one village to just building and leveling defensive troops then everyone with five villages devoting two to just defensive troops, and anyone with seven devoting three villages to defensive troops.
As far as offensive capabilities I would sugest, at three villages, one for cav and one for infantry then at five villages two for cav and two for infantry and at seven three and three while the capital is used for the production of everything since the fields can be upgraded indefinately. I woulod also sugest that the capital is where the vast majority of seige equipment is produced.
