I still don't really see the value of making warlord units.
If you use them to take out an enemies best defender's, chances are you're going to get about 70-80% odds. If you're lucky, your warlord is going to take out 5 units before he dies: Hardly an efficient use. You could take out the same 5 units, by suiciding some city raiders into them, and then cleaning up with the rest of the stack.
But then.... like your example where you had to re-group, I may be biased by my recent game where I had to defend against a full scale preatorian attack.
