Ahem...is this question too silly for this forum? 

There is no question too silly for this forum, I should know.
A feigned flight move I feel should be nearly exactly like a regular flee, the only difference is that it flees towards arrival or own table edge instead of away from enemy.
It should flee in a direction avoiding friends it can not pass though pivoting to avoid this unless this would take it closer to known enemy, then it will burst through friends in it's path.
Sorry if this is confusing
I think all the usual respondants are thinking about DBMM 1.1 and any ramifications and all of this (Feigned flight flee moves) may change to sort out any or cause problems.
Well at least I gave it a stab
