Creature Companions - Modifiers

[Laendra Silverleaf]

So, I understand that the base skill bonus would be a set value at a given level. Ability modifiers should IMHO affect those base values.

Likewise, Strength bonus should affect melee attacks instead of just melee damage.

Oversight?

Ability modifiers don't apply separately to skill scores on any other NPC. Why would they apply here?
