Purely hypothetical question, but here goes. Let's say you were, I dunno, maybe EA Atlantis. And you want to attack, hmmmm, uh... how about EA Vannheim. And (keeping in mind this is purely hypothetical) let's say they were handing you your scaly dorsal fin whenever you attacked them, either with thugs, or conventional armies. I'm assuming serious combined arms or outright SCs would be the necessary angle of attack, but what are the best ways to take them down in this (purely hypothetical) case?
(Hatethevanns. Hatehatehate. There's a reason I've been known to set their AI bonus lower than everyone else when I do SP...)
[Clarification: My normal SP solution involves truly massive HI formations, possibly with lightening resistance. However, Atlantian access to air magic is beyond pitiful, and I'm having trouble massing infantry on the same scale the Vanns are. Is there a relatively simple solution I'm missing beyond giving up on fighting back while slowly massing hordes of War Shamblers (with non-air elemental support) to retake the land I'm losing?]
