Double Initiator, double duelist comps are pretty common ie. VS bind comp: Jett(BuZz), Raze(Rb), Breach(Stax), Skye(Lakia), Astra(MaKo).
TSM triple duelist comp in first strike on split is 100% meta so idk what u mean by teams only run 1-1-1-2 comps.
Also Triple Initiators were really well done by Ghost on Haven against Faze? I think. Lol that retake.
Double smoke comps are also pretty common due to Astra-Viper being prevalent on maps such as Bind, Split, Haven, Ascent and literally everything.
And Brim-Viper comps were really common on bind such as Fnatic's iconic bind comp: Brim, Viper, Skye, Raze, Sova
