Ever since Spartacus was released ppl have been using his spells to beat everyone's defenses before launching troops. No problem, but the defending general doesn't start casting his spells until troops are launched. So if you have Maximus (with healing) set to defend he should be able to heal the damage caused by Sparticus BEFORE troops get launched. Plus, he'll heal a set of walls while the defense is getting hammered elsewhere. :facepalm:
Defending general's AI needs some serious help. It sucks.
