Fire and Flee

[tinkthank]

Anyone use this command? No sorry stupid question: How do you make the best use of this command, in what situations?

I have had pretty much zero success with Caelum, which is a shame; I just cant keep those flying infantries from impaling themselves on enemy pikes too quickly. "Hold and Attack" is too short for me, I'd like a "Hold Longer and Attack" too.

But I thought "Fire and Flee" might be nice, because Illwinter explicity writes in the only description of Caleum (in the Choose Nation screen) that they are fond of "hit and run" tactics. Now what could these be? I figured I could use some "fire and flee". But had also zero success with those. My great archers leave the field, and then my remaining troops teleport/fly to the enemy and get wiped out by all but wimps.

So your general feedback is much appreciated, as always. Thanks in advance.
