As far as rules go, I think the flanking should be done before getting too close to enemy. Scout allows creating confusion to enemy with they ZoC currently and by removing that, you'd downgrade their abilities a bit. I think it's better to allow some tricks to enemy as well .

So in short: A unit moves or already is in an enemy unit's ZoC and it's formation takes an assault action it is forced to move into BtB and can't just stay where it is and FF?
So in order to use it's FF value (unless it is a Skimmer) the unit has to be 5 (10 in the case of Scouts)or more cm away from any enemy unit ?

Here's a conceptual explanation of why you "have to base" when in a ZoC, particularly a scouts ZoC, and ways to mitigate it that I wrote in another thread:

[quote]This is normally not a "problem" as the enemy ZoC is only 5cm, so there's no need to base them, unless you've somehow started your activation within it; this "must base" only happens with scouts' 10cm ZoC as that represents the "possible" locations of the scouting troops.  

The soldiers "on the ground" don't have the god's eye view the players do, nor do they "take turns", as the players do, nor do they stand on little rectangles like the models do.  The scouts' extended ZoC is similar to the concept of an electron probabilty cloud, the actual scouts are "somewhere in there", which is why the enemy has to react differently to them than more closely operating enemy troops.  It's an abstraction of the "unknown" location of the units for the troops on the ground.  As they move around in the "scout probability cloud", there's a high likelihood of them making dangerously close contact with the scouting elements; the game represents this by forcing you to base in this situation.

Because an exception trumps a generalization? It's fairly standard for a rules set.

It's been clarified that "beginning in a ZoC" and "entering a ZoC" are considered identical if engaging the unit whose ZoC you are in.

A unit is not required to move in an engagement, UNLESS it enters/begins in ZoC. Then it MUST, to the limits of it's movement. It's fairly well defined with the above clarification.

You seem hung up on the 'move normally' statement. I believe this refers to everything that doesn't contradict the initially referencing rule (turning, other units blocking, coherency etc).
