Then I didn't express myself not well enough. I meant that in it's former state the mod was not as usable as it should be. And those hidden dependencies were one of the reasons amongst several why she probably did the NTotSC rework at all.
But just to give a short overview what will be "missing":
Tytus won't have a copy of the Black Swan Armor (aka the charisma armor from IWD) from TDD but a generic Plate Mail.
Mariel won't have a copy of the Rogue's Cowl (another item from IWD) from TDD.
Mommy won't have a copy of the Boots of the Forgotten Ones.
The changed scripts are a good thing, as it prevents no enemy actions in case BP is not installed. Moreover, the change to standard scripts still leaves the option open to modify the scripts with either BP or SCS.
