Why not let Organised live up to it's name?

Organise the units in the stack.
The stack moves at the average speed of all units in it.

So simple...

That leaves Organised as a trait without having a stack of doom zipping around like on crack.

A single slow unit would not instantly axe the speed of the whole stack. With a few fast units in there, it would be... somewhat okay.

Boosting the sovereign's movement speed would still speed up the whole stack but it would take an increase of +6 sov speed to speed up a stack of 5 by 1 full movement point.

Yes, you could have 5 one-man squads in the stack with all movement buffs. That would speed things up. But it still wouldn't be 8 squares per turn.
And what if you actually meet an army that fights back? Your one-man squads would be so many kinds of useless so you'd have one seriously weak army stack.

I'd think that would be a 5 point trait or so. It's nowhere close to the original Organised...
