Miss Fortune getting a buff instead of a nerf if you think logically!!!
So in patch 7.5 Riot is thinking they are nerfing Miss Fortune by REMOVING: If double up's first shot kills the target the second shot will hit for 50% increased damage aka a CRIT HIT.
If a person looks at the facts on this and thinks a little they will notice the buff to miss fortune's Q- Double up
Currently in ranked and especially in pro play if a ADC chooses Miss Fortune their ultimate goal is to wait for a minion to be low with a champion behind it to punish with a double up. This sometimes takes 1-2 minutes to combo perfectly in a match especially in pro play. That means a skill that has a cooldown of 6-7 seconds early game is being used maybe once or twice per minute where if you abused the double up knowing the enemy adc has to move in to last hit you could very easily get in 6 or 7 uses in a minute. So lets do some math
a LVL 3 double up by lvl 5 which is indefinitely still in the laning phase will give you 5-6 shots per minute if you can manage your mana with masteries and maybe an item. Knowing the 2nd hit will do 100+ (100% bonus attack damage)+ 60% love tap damage if you bonus damage is 48 1 item plus starter item each hit will smack the enemy for 100 + 48 + 58 (base 49 plus additional 48 X 0.6) = 206 before armor( a low number for adc's) is factored in.
with the 50% crit bonus that's 309 per hit if minion killed
because people wait for the perfect chance to get that crit hit in they waist many chances to just hit the adc with a second hit dealing damage chunking the enemy's health. in a 2 to 3 minute time frame high lvl players can expect to use it 3 or 4 times because they wont use it if the minion is at perfect health but the champions is not in range or vice versa. that gives a high side of 4 X 309 = 1,236 damage in about 3 minute span using double up.
When the crit bonus goes away the need to wait for the perfect double up is gone and spamming the skill will be more natural. With mana costs recognized and the fact your enemy adc needs to move in range to last hit at least 3 of your minions you can get an easy 11-12 shots in the same time spam without the mana mastery would be approximately 11X206 or 2.266 damage.
So taking into account that a player probably wont use the skill 24/7 under either condition you can still expect to easily get 50-70% more damage in without the crit buff on the skill because theirs no longer a need to wait for crits.
