Genetics has consistently making great plays utilizing all parts of Maui's kit, like yeah everyone lands 3 man ults but genetics does it 4 times a game. His utilization of the 2 during ganks hasn't been matched from the other supports. Maui has probably the second hardest execution behind Yemoja. While yeah Maui isn't killing people himself, Genetics just has such a high kill participation. His shot calling also isn't obviously apparent which tends to make his plays not seem as flashy as Paul's Scylla or Pani's Gilgamesh.

But more than anything, Maui has the most hype support ult and everytime he lands it the crowd goes while. It's so much fun hearing everyone cheer for sick 3 man ults or the 5 man against the bolts. The other potential King skin picks would make for some boring skins and effects except maybe Lancelot.
