The Ultimate Team Comp, and "Team Fight"

So imagine a team that goes like this. Top: Kennen Mid: Yasuo Jungle: Zac Sup: Ivern/Nami ADC: Jhin/Cait or anything tbh Basically the team fights depending on the situation can mainly go these 3-4 ways. Scenario 1: All 5 Players On Each Team Are Grouped Together. Zac E's In To 4-5 of the enemy team which are clumped up. Yasuo ult's or gets in position to ult, if necessary Nami can ult to sustain the airborneness thats a word now so Yas can ult... After Yasuo ults, Kennen will already be near the enemy team and will then Ult stunning them in position. If enemy team isn't already dead.. Zac ults divided enemy team up and shoves them out. ADC and rest of team can pick off remaining stragglers. Scenario 2: All 10 players are together. Zac E, Into Nami Ult, Into Yas And Kennen Ult, Jhin Curtain Call Cleanup. Scenario 3: Zac E, Ivern Q, Yas Hits q'ed enemy and is moved towards enemies, is now in range for ult, ults, kennen does same and ults. Jhin/Cait or any adc clean up and dmg while enemy team is busy. Scenario 4: But, but Winston, no one asks because no one knows who I am, what if they have cc or QSS? Mercurial? Too bad, too much cc. Honestly between Zac, Nami/Ivern, Yas, Kennen, Some sort of ADC, I don't think the 1 QSS proc or Mercurial will do much. What if they just don't clump up? Don't group? Too bad. Idk what this is just thought of the team comp, as my friend and I play Zac, and Yas a lot in ranked. I play Zac mainly, he plays the Yasuo, and sometimes we'll get a kennen (pst.. never they always get the Kennen main who proceeds to 5 man ult my team and we lose) lol so uh no closer bye....
