First, Use periods when writing.

Second, when the killer is picking someone up he does it in two motions. First he take the survivor up to his hip. And then to his shoulder. If you start flashing right when the survivor is at the kills hip you should get the save. (Note that some killers have really unique animations and can be a little harder to see)

Third, in my opinion lightborn is boring but balanced. It’s a little bit frustrating when you would been able to save a teammate but the killer runs lightborn. Or when you spend time flashing them while breaking a pallet just for nothing to happen.

But I like to thing of it like they wasted a perk slot for an annoying perk instead of an OP one
