Why sign Sp9rk1e and Doha? aight this might sound dumb but what's the point of dallas signing both sp9rk1e and doha?

the venn diagram of their hero pools is literally a circle inside a slightly bigger circle (just because of doha actually looking competent on sombra)

don't get me wrong it's pretty sick to have both of them but literally the only meta where both play is mei doom, hackfist/sombra genji, or a pharah comp with another projectile hero, none of which have been meta this season except for sombra genji (and genji is most likely not becoming meta again for a while)

am i dumb or does this make no sense
