OK, lets do some math - we have Miss Fortune level 6(0 AP). She has one rank in W and E and 3 in Q, one in ult.

1. A Old Miss Fortune uses E - R combo. She deals 400 physical damage and magical damage equal to 90 and 198% AD(Impure shots).

1. B Old Miss Fortune uses R without E. She deals 400 physical damage and magical damage equal to and 198% AD(Impure shots).

E did magical damage equal to 90, thats it, nothing more.

...but...

2. A New MF uses E-R combo. She deals 440 physical damage and magical damage equal to 90 and 210% AD (Impure shots - 10, 20, 30, 30*5 per wave) as magic damage.

2. B New MF uses just R. She deals 440 physical damage and magical damage equal to 165%. Thanks to E, damage was increased by 90 + 45%AD magic damage.

Standing in both E and R allowed quite big damage raise, making it as if it actually had 45% AD scaling. And due to passive of W, part of bonus MR of target is ignored.

For 2nd and 3rd levels of ultimate, this increases to 60%/65% pseudo AD scaling.

Or, if you are autoattacking target inside E, you create pseudo AD scaling. For first few attacks, this ad scaling is:

1 attack: 5%AD bonus damage; 2 attacks: 15% AD bonus damage; 3 attacks: 30% AD bonus damage. 4 attacks 40(ult rank 1) or 45(ult rank 2)% AD bonus damage.

That is, if you do something like autoattack Q autoattack autoattack to target inside of Make it rain, you dealt 45% AD magic damage bonus.

This is however not free scaling, it requires you to fight against enemy. I believe this is fair, since MF already has high AD scalings, so this actually gives some aditional power to E that it needs.
