Also what does everyone think of allowing swords?
I personally would love that. I enjoy sword fighting. But others may think of it as an imbalance.
I don't see pistols being a problem. Not anymore of a problem than people shooting muskets.
Also, you should be able to set number of Captains per unit. So you could set it to 2 and there would be a max of 6 or 8 captains for most factions. or you could set it to 1 for less.
As a side note, maybe look into NFO hosting for a server. I had a ddos attack happen and they took care of it immediately. It may be more than what you pay for now though. And I'm not sure if it's the type of server you're looking for. But I have a 200 man event hosted on my server twice a week with no problems.
