buffed yes: gunslinger double or triple shots all apply on hit effects like mana-on-hit
sorc mf
and that Tear+BF

They need to buff MF's IQ from -2 to at least 4.

patch 9.14

Miss Fortune
Ability targeting: random enemy ⇒ current attack target


So in the end its about your IQ in putting your units down, not MF IQ
1)MF may target the assasin that is behind her, so make sure there is a allie or wall behind MF
2)MF may target the target of blitzzcrank, so make sure blitzcrank is not behind mf

Good point, I think one issue still is mf before you have good items or items at all on her. Cause if she has no mana you dont know when she will ult. At least not for certain.
