From the BRB updates. Looks like GW is addressing some things:
Q: When taking a Leadership test, sometimes you have to take it on
your unmodified leadership. What is your unmodified leadership?
(p10)
A: Your unmodified Leadership is the highest Leadership
characteristic in the unit. Do not include any modifiers from
any source, for example, Strength in Numbers, Inspiring
Presence or the Doom and Darkness spell.
Q. For characteristic tests, is the best value in the unit always
used? (p10)
A. If the unit is required to take a characteristic test, the best
value in the unit is used. If every model in a unit is required
to take a characteristic test, then each model uses its own best
value instead.
Q: When does a weapon that gives a bonus to a characteristic give
that bonus?(p4)
A: Most weapons, including magic weapons, state when the
bonus is given. For example, a model with the Fencer’s
Blades will always have Weapon Skill 10 whilst a model with
a great weapon will only have +2 Strength when striking an
enemy in close combat. When a weapon does not say when
the characteristic bonus applies, then it only applies when
striking, or being struck, in close combat.
Q: Will a unit automatically pass a characteristic test if any model
in the unit has the ability to do so? (p10)
A: No, every model in the unit must have the ability to
automatically pass the characteristic test for the unit to pass it
automatically.
Looks like several more are included as well...
