On the other hand, I think defensive is best if you've brought your Phalanxes (att:1, def:4) to an attack. They'd be used much better if they were defending, so you minimize the number of times they're selected to participate in the attack. ...Or just don't include your phalanxes when attacking. Also, if you're being attacked, and you're trying to get that extra hour of time for reinforcements to arrive from other players, I think you'd draw out the battle time, just with worse odds.
I haven't had enough battle time to really get a feel for if I'm right or not, so take all this with a grain of salt.
