multiplayer atlantis strategy?

[ElectronicEagle]

Sorry, atlantis middle era. We're on turn 7 and I've had 4 negative unrest events (no revolts so far). Does this seem unusual?

What are the best troops? Shamblers look promising, but they keep dying in large numbers.

What's the best ratio of commanders to troops? I think the reason I just lost a major battle was that one of my 2 commanders died and all his troops routed.
