And?
Just to prove that this concept is getting old as fuck.
Their new champ has it too. 
Let's see how many champs have this "original" mechanic in their kit:

Very original
A lot of those 3 hit mechanics are very different from each other though. 3 hit mechanics are used to gate champions power without giving them up up front. Imagine if Diana could cleave every auto attack instead of every 3. Imagine if Vayne could proc silver bolts every auto attack. 3 hits just happens to be the perfect number to gate certain effects without making them too weak or two powerful.
Let's also not forget the fact that a lot of these 3 hit mechanics are still very different in gameplay. Aatrox is able to get some insane lifesteal or extra damage at the cost of his. Vayne gets true damage on hers so she can shread tanks. Varus's 3 hit allows him to proc extra damage with other abilities, and he is able to proc on multiple people at once. Let's not forget the most unique of all, Tahm Kench.
You can easily call Tahm Kench's 3 hit passive a boring mechanic, but I would easily disagree. You call being able to devourer enemy champions a bland and boring mechanic. Hitting that 3 hit passive also allows him to proc a hefty stun at range.
Yeah, anyone can look at these and say the comonality between them (3 hits), but the fact of the matter is most of those interact differently. Tahm Kench's passive is sure as hell different than Aatrox's, which is also different from Xin Zhao's.
P.S. Why in the hell is
up there? 3 auto attacks at max attack speed is way different than a typical 3 hit passive.
Well, I can see why Gypsylord does it, it's unique for his(?) champions to have them. Kind of like a style that he likes, and that others occasionally do but not always. As much as people like to complain, three hit passives and %hp damage have their place. Some feel tacked on Gypsy's champions (specifically Vi's %hp damage, I feel like the three hit proc is good enough due to her only needing to land her QaaE combo; Ekko's W passive; possibly Gnar's W?) but some do make sense at least to me (Again, Vi W three hits, Jinx's Q, Jinx's R makes some sense since it's an execute not an initiator, and Ekko's real passive).
Some of them may and some probably are (I mean, I might be biased but I'm not going to lie) overtuned, and while they may not be flawless I do feel like Gypsylord was right on using that mechanic about 50% of the time at least.
It's a concept used a lot because of the league of tanks
3 is the magic number.
Jinx doesn't have a three hit passive, honey.
Mini-gun Q.
Three attacks for max attack speed steroid.
Try again next time.
I know how her Q works, but that's not how I would define a three-hit passive, since the first two hits also do something. I'd define a three-hit passive as something where if you can hit all three, you get something extra, like Vayne's silver bolts or Kindred's Mounting Dread. Would you describe Orianna's passive as a three-hit passive, or Jax's as a six-hit one?
