MF Ult damage?
75% AD (+ 20% AP) physical damage.
Each wave can critically strike, dealing 20% × (1 + bonus critical damage) bonus damage.
Waves: 12/14/16
If an MF at level 18 had about, 250 AD, each wave would deal about 187.5 damage. At level 16, the ult fires 16 waves, meaning: 187.5 x 16... 3000 damage. Not even factoring in the possible crit chance per wave, this does double Lucian's ultimate damage being 1500 maximum with the same amount of AD, WHILE being able to hit all 5 enemies at once.
And yeah, maybe I'm salty that I just played a game in which the enemy 4/7 MF with
got a 3v5 Penta on us with nothing but her ult, a Q and an AA, but she also has the highest win rate for an ADC, while having the 4th highest play rate as well.
