I mentioned Thermopylae;)

It's about the same sort of figures for Roman warfare IIRC, maybe a little higher but not much. Eitherway i could deal with say 20/10 or 30/15 ratios, it's the total annhilation that gets me at present

from a position of complete ignorance it strikes me that increasing defence ratings of routers would be the way to go.

How about increasing the speed of routers - is that possible. Simulates the throwing away of shields etc to run faster than the pursuers :)
