heres a good strategy thats saved my but countless times:whenever you send a relatively slow guy into battle (such as the flailer) send someone fast (preferably a spearman) right after that in the same row; that way your fast,weak guy can take the damage from archers and other units while your slower, more powerful guy finishes whoever the fast guy is batling off it prevents your powerful guy from getting hit until the spearman dies. hope that helps anyone :)
