Mage Fortune does actually more Attack damage than ADC MF

She doesn`t need boots x3 cuz of her passive.
AOE SHRED and her Ulti will be soo Scary :3.
Lets say Mf has 600 AP
her ulti at max rank will do
1000+(600x160%)= 1000+960= 1960 physical damage because her R convert AP to do physical damage.
not only that, but her impure shot does 6% of her ad at max stacks it does 30% of her Ad.
6% x 5 stacks = 30%
now her base AD is 103,54 at lv 18
black cleaver is 40 and last whisper is 40 attack damage
for a total of = 80 + 103,54 = 183,54 AD and 600 AP
Maximum damage of Stack is: 384% which is
384% of 183,54= 704,79 magic damage
soo her ulti in total will do 1960 physical damage + 704,79 magic damage.
now remember that black cleaver can shred up to 30% armor and her last whisper shred for a flat amount of 35%
I didn`t include the masteries bonus too
For an AD version that want to do Magic damage is:

and just laugh while you troll.
or
on her?
can also be considered.
works well with her E, and
or
.
This is for pure AP, though. Not set in stone, of course.
