the synergy im refering to is the gold % bonus (order +production) together with growth (constant % bonus +population increasing every turn). Im not sure if the battle mages of ma agartha is so powerful compared to the other nations, not if you factor in the price. They are not bad either i guess, but i would not rate them in the top 20 (among the 62 available).

There are ways for agartha to deal with raiding even if they are few, one way is to use earth attacks to just kill off the commanders (just get 1 earth bonus on your e3 mages).
